1. GermGuardian AC4100 Air Purifier

GermGuardian AC4100 Air Purifier Review

GermGuardian AC4100 Features And Build Quality

At a mere 6.5 x 11 x 7.5 in dimension, GermGuardian AC4100 is a very compact air purifier similar to the size of a single speaker. The 4.85 lb weight is equally light for carrying around for room-to-room cleaning despite the lack of a proper handle. The versatility continues that AC4100 can work in vertical or horizontal positions without any airflow disruption. Leave it on the desk during the day and bring it to the nightstand during sleep. At the rear, you will find the air inlet covering most parts of the air purifier, and the air outlet is the other way around. Overall the build quality is solid despite the heavy reliance on plastic. No issue with the durability as the air purifier will hold everything tightly together.

GermGuardian AC4100 controls

On to the usability. GermGuardian AC4100 is very simple to use as there is only one front dial knob for 3 fan speed control and UV-light on/ off button. Choose your desired speed, and the air purifier will handle the rest. At the back, you have the Filter Reminder back wheel that requires manual adjustment. There are 4 felt pads you can stick it depending on what position you want the air purifier to operate in. Other than that, there is nothing much in it besides the 4-stage filtration and a standard 1-year warranty.

GermGuardian AC4100 Filtration, Air Performance, And Noise

As an entry-level compact air purifier, AC4100 estimated 60 sq. ft. purifying coverage is poor. It is meant to be used as close to the pollution sources as possible. Best suited in close range like desktop, bedside, or next to a litter tray. The 3-speed airflow delivery rate isn't any better, although that is expected given the limited performance of the air purifier. No official CADR, but it should follow a similarly low output pattern.

GermGuardian AC4100

As mentioned earlier, GermGuardian AC4100 is a 4-stage filtration (3-stage officially) at a very compressed body. You have the initial carbon pre-filter that handles large particles and light smoke/odor pollutants. With those pesky particles out of the way, the HEPA filter would uninterruptedly capture smaller micron-size particles at 99% efficiency down to 2 microns. As for notorious and tricky allergens, including bacteria and viruses, you have the UVC-light + PCO filter standing by for the last round of elimination before releasing the purified air.

GermGuardian AC4100 suppose to have a very decent noise level given its low airflow delivery rate, but we find that it's rather loud at second speed onwards when placed close to you. Keep it at the lowest speed if you want noiseless operation during bedtime. On the flip side, power consumption is low across all speeds; even the air purifier does not have any eco-ness technology. You can leave it running 24x7 without feeling a pinch on your utility bill.

GermGuardian AC4100

GermGuardian AC4100 Pricing, Maintenance, And Drawbacks

Besides the different variants from GermGuardian AC4100, it's the only affordable air purifier with UV-C light technology for under $60 after discounts. You have to compromise with a weaker airflow output and dated features that can be annoying at times. While the comprehensive 4-stage filtration is good to have, it does add up to the annual filter maintenance cost unless you want to skip the UV-C bulb. Another thing is the combination filter E set cannot be purchased separately; you have to replace it every 6 months on regular use.

Air purifier keeps getting cheaper and cheaper every day. GermGuardian AC4100 delivers what the consumer need. A practical, effective dust/ pet removal air cleaner at a fraction of the cost. If you want something that is dirt cheap and does not mind the relatively short 1-year warranty, go for it.

2. GermGuardian AC5250PT Air Purifier

GermGuardian AC5250PT Air Purifier Review

GermGuardian AC5250PT Features And Build Quality

One of the best value pet air purifiers engineered with a 5-stage filtration setup, including a germ-killing antimicrobial. GermGuardian AC5250PT Pet Pure stands "tall" with its all-around versatility. At 6.1 x 27.3 x 9.5 in and 10.5 lb, GermGuardian AC5250PT is not particularly huge or heavy for an air purifier. You can still carry it from room to room purifying, albeit it can be cumbersome due to the tower form factor. There are a few premium touches that we like, notably the top chrome with a light bar. The bottom base helps stabilize the slim structure, while a carrying handle is at the top back. The Air inlet is located at the back, and clean air is dispersed at the front, a typical air purifier setup. On the whole, the build quality is good, with plasticky housing that shows no sign of leakage. Icing to the cake is the 5 years official warranty covering any manufacturing defects. Rare for an air purifier of this segment.

GermGuardian AC5250PT controls

Operating the air purifier is dead easy that even a 3 years old could understand. You have the main power button that circles around the display and a fan speed button that will cycle between 1-5 speeds. The UV-C button activates/ deactivates the ultraviolet light; turn it off if you want 100% mechanical filtration. The customizable timer can be set between 1-8 hours. Right above all is a small Filter Reset button that is only used after changing the filter. You will need to press it with a small object like a pen tip or paper clip when the HEPA light flashes continuously.

GermGuardian AC5250PT 180 sq. ft. purifying coverage is targeted for small to medium range room size. Not the most impressive, but it will get the job done. Across the 5-fan speed, we did not encounter any slowdown or unstable distribution. If you plan to use it in an open space area such as a dining room, basement, garage, or living hall, max speed is a must. The air purifier will do just fine for night use in the bedroom.

Besides the 116 cfm smoke CADR, we do not have the official CADR figures for pollen and smoke. In theory, it should be around the same region or at least not too far off. It's certainly not the best output, but the air purifier will have no issue dealing with large to fine particles.

GermGuardian AC5250PT Filter

GermGuardian AC5250PT Filtration, Air Performance, And Noise

Here's where all the magic happens. A 4-5-stage filtration setup, depending on how you look at it, GermGuardian AC5250PT 3-in-1 utilizes a dual charcoal pre-filter that is common in this segment. The pre-filter will trap large particles and act as a shield for the HEPA filter from being damaged by dust, debris, or fiber. For microbes, you'll have the HEPA filter standing by to capture microscopic particles bypassing the pre-filter. The HEPA is also coated with a Pet Pure antimicrobial that inhibits the growth of microorganisms like mold, bacteria, and viruses. Last but not least, the optional UV light emits short-wavelength radiation to eliminate germs and viruses, leaving no traces behind.

Another hallmark of GermGuardian AC5250PT is the whisper-quiet operation. Our test unit runs silently at most speeds, standard across all GermGuardian air purifiers, including its predecessor AC4825. Power consumption is generally low; it varies on operational hours, lifestyle, and surrounding environment. Sadly, there is no Auto/ Sleep mode to help improve energy efficiency.

GermGuardian AC5250PT is cheap (under $150 after sales) for a 5-stage tower air purifier. It is highly functional and comes with the completion filtration set from HEPA filter, UV-light, and Pet Pure antimicrobial. A worthy upgrade over the previous GermGuardian AC4825. Annual filter replacement is another story. While the filter is not too costly to replace and find between 53-80, other cost-effective models from Honeywell or Levoit can be beneficial in the long run. In 2-3 years, you can purchase a brand-new air purifier with a complete set of filters. To cut down on the filter cost, the UV light can be disabled when it is not needed.

GermGuardian AC5250PT

GermGuardian AC5250PT Pricing, Maintenance, And Drawbacks

For a budget-friendly model, there are bound to be some drawbacks. GermGuardian AC5250PT air purifier is restricted with its purifying coverage with limited airflow delivery rate. The short 6 months of filter usage life don't help either, especially with its filter replacement cost (with Pet Pure filter C). The troublesome filter reset requires small objects like a pen tip to reset the button. We will give the lack of air quality sensors and Auto mode a pass but using charcoal pre-filter rather than a dedicated activated carbon filter is disappointing.

Ignoring the cons, GermGuardian AC5250PT is the perfect pet tower air purifier if you need something inexpensive yet removes airborne pollutants well. It is ideal for city folks who require a HEPA air purifier in their limited space abode. If you like or have used AC8425, you will be familiar with it.

3. GermGuardian AC9200WCA Air Purifier

GermGuardian AC9200WCA Air Purifier Review

GermGuardian AC9200WCA Features And Build Quality

GermGuardian AC9200WCA is one of the few higher-end console air purifiers in the GermGuardian lineup. An ideal choice for most city families requires a reliable and durable air purifier.

House in a 17 x 27 x 9.8 inches dimension body and 20.7 lb weight, it is considerably larger than your typical GermGuardian HEPA tower air purifier. It is not the most convenient unit to move around the house. The clean, white front panel with side inlets and back outlet does give it a nice modern feel. Build quality is probably its biggest high point, as GermGuardian AC9200WCA feels more upscale and well put together like a premium air purifier. Expect no leakage and harmful byproducts off-gassing from this beautiful machine. CARB-approved and 3 years warranty come standard.

Continue on. The touch control panel is at the top, hidden from eye view. You can adjust the air purifier 3 fan speeds, 6 hours programmable timer, UV-C, and ionizer (both can be disabled). Most people will keep UV-C and the ionizer active unless they want 100% ozone-free filtration. The filter change indicator will alert you to replace the filter when it is due. A big step-up from AC4100 manual reminder wheel. Unfortunately, there is no auto mode and AQI here.

The advantage of a console air purifier is performance tends to be better than a tabletop/ tower air purifier. No exception with GermGuardian AC9200WCA. The punchy airflow delivery rate allows a wide 378 sq. ft. air cleaning coverage. Ideal for medium to large room sizes, including living room, master bedroom, garage, basement, and kitchen. It will also fit nicely in an office, nursery home, studio, and small apartment. The purifying coverage will not be impacted by the usage of UV-C or ionizer technology.

GermGuardian AC9200WCA Filtration, Air Performance, And Noise

Tally with the airflow performance, GermGuardian AC9200WCA CADR figures are on the high side with dust at 310 cfm, Pollen at 346 cfm, and smoke at 244 cfm. Impressive, particularly against non-smoke particles, and no other GermGuardian even comes close to this figure. Feel free to compare it with other air purifiers via the table below.

Let's talk about filters. GermGuardian AC9200WCA has one of the most complete filtration setups in this segment. First is the permanent pre-filter that captures large particles i.e. dust, debris, and hair, while prolonging the HEPA filter lifespan. The HEPA filter works exactly as it should by trapping micron-sized household allergens. A standalone Activated Carbon Filter would dedicatedly handle smoke and stinky ol' odors from cooking, cigarette, CO2, and VOCs. The optional germ-killing UV-C light emits short-wavelength radiation to sanitize pathogens like mold, germs, bacteria, and viruses. Lastly, the ionizer release negative ions that attach to positive ion pollutants in the air, pulling them down for the filter to capture. The cleaning cycle will continue to filter and provide fresh air in the room.

GermGuardian AC9200WCA noise level is not the lowest in its range despite the better airflow performance. You could still utilize the air purifier in the bedroom at a low speed with a noise output of under 30 dB. Power consumption is also reasonable despite the stronger airflow output. Place it further away to reduce the spinning fan's noise distraction.

GermGuardian AC9200WCA Pricing, Maintenance, And Drawbacks

Here's where things get tricky. GermGuardian AC9200WCA +-300 price point is significantly more expensive compared with similar range air purifiers such as Winix HR900 yet lacks any autonomous feature. You do get an outstanding CADR return with a comprehensive 5-stage filtration that is unique on its own. Perhaps more controversial is the combo filter pack, which can cost more than $100 if you replace the UV-C light together. Always look into the filter replacement cost before deciding on an air cleaner.

To conclude, GermGuardian AC9200WCA is a proven and effective HEPA air purifier that can swiftly improve your indoor air quality. It can be expensive, bulky, and loud at times, but nothing beats breathing in clean, healthy air.

4. GermGuardian GG1000 Pluggable Air Purifier

GermGuardian GG1000 Pluggable Air Purifier & Sanitizer Review

GermGuardian GG1000 Pluggable Features And Build Quality

When GermGuardian GG1000 pluggable UV-C sanitizer was first launched, we touted this as the innovative small appliance of the year. It is the perfect compact UV sanitizer that cleans the air simply by plugging it into a wall outlet. At around 1.13 pounds in weight, 3.2 inches in width, and 7.5 inches in height, it is a space-saver that takes up very little of your interior space. If you are a frequent traveler, GermGuardian GG1000 can easily be packed into your backpack, even on a short getaway.

One of the most exciting aspects of GermGuardian GG1000 is its unique hourglass design. It looks elegant and premium with metallic touch despite the fact that it is made out of plastic. Build quality is good, with no signs of byproduct leakage detected. The thin air inlet is located at the bottom front with an air outlet at the usual top spot for better distribution. You will not find any complication controls here, as GG1000 is a basic plug-and-play model.

Moving to reliability, GermGuardian GG1000 UV-C Sanitizer comes with a 1-year limited warranty with US-based tech support rather than a third-party country. To ensure the filter-free UV sanitizer is in tip-top condition, do not place it under direct sunlight or near flammable items like insecticides. Also, make sure the sofa or bed is not impeding the airflow distribution.

GermGuardian GG1000 Filtration, Air Performance, And Noise

As a pluggable air purifier & sanitizer, GermGuardian GG1000 airflow distribution is somewhat limited. The 56 square feet recommended room size can only cover a small area. Adding the lack of a big motor fan to draw airborne pollutants in, you will need multiple units to purify the air in a large room. CADR is unavailable as the UV sanitizer does not have a filter for proper testing. GermGuardian GG1000 UV sanitizer is ideal in the office, bedroom, kitchen, bathroom, or near the litter box.

So what do you get under 40 dollars? A highly dependable UV-C light technology with Titanium Dioxide. GermGuardian GG1000 UV sanitizer can effectively eliminate bacteria, and viruses in the air, including influenza, staph, and rhinovirus. By permanently killing germs, there is zero chance of the microorganisms growing and spreading. It can reduce household smoke and odors from mold, pets, food, diaper pail. On paper, it can also remove VOCs and cigarette fumes at a limited capacity. If you are a smoker, have pets, or have a smelly toilet, GermGuardian GG1000 will fit right in. You will experience fewer allergy symptoms like sneezing, scratchy throat, skin rash, and headache.

Overall, GermGuardian GG1000 room air sanitizer can make a difference in your indoor air quality. Using the safe UV-C light technology, it does not produce harmful byproducts like ozone which many dreaded. Just take extra caution when using a UV light as improper use can cause cancer or birth defects, as explained in California Proposition 65.

With no filter, big motor fan, or fan speed adjustment, GermGuardian GG1100 UV-C Air Sanitizer produces zero noise throughout the entire operation. You can breathe and sleep better even with the air purifier running beside you. As for energy efficiency, the 120 Volt AC/ 60 Hertz power usage is low that will not create a burden on your electricity bill. You can safely leave it on all day while you go on with your daily life. At an average of 3.5 watts output, power usage is only $0.4 monthly or $4.8 yearly with 24 hours of runtime.

GermGuardian GG1000 Pricing, Maintenance, And Drawbacks

For less than 40 dollars, GermGuardian GG1000 Pluggable Air Sanitizer is affordable and comes with a standard UV light bulb. You do have to replace the light bulb every 6 to 12 months, but the replacement cost is quite reasonable. Being a pluggable filterless air purifier, most people will compare this with the newer GG1100 version. As alluded to earlier, GermGuardian GG1000 has been in the market for some time, so it might not be that easy to track this model. So if you don't mind the older design, GG1000 is cheaper and works exactly like the newer version.

The world's famous pluggable UV-C air purifier that will not cost you a fortune. GermGuardian GG1000 is one of the best plug-in air sanitizers we have ever used. It is affordable, compact, hassle-free, and most importantly, it works. Consider the newer GG1000 too, before purchasing one.

5. GermGuardian GG1100W/ GG1100B Air Purifier

GermGuardian GG1100 Elite Review

GermGuardian GG1100W/ GG1100B Features And Build Quality

An improved, filter-free, pluggable air sanitizer over GG1000. Guardian Technologies is the king of innovative small appliances that can improve our health. No exception with GermGuardian GG1100 Elite UV-C Sanitizer. A compact yet powerful air cleaning device that can provide fresh air from any wall outlet. At a mere 0.7 pounds in weight, 3.5 inches in diameter, and 6.75 inches in height, you can place it anywhere in the room without being too obstructive. In fact, you can even pack this 7-inch air sanitizer in your backpack during travel.

As for design, there are 2 color options: white (GG1100W) and black (GG1100B). The clean white design has a glowing circle ring at the front, letting you know the device is running. The plastic exterior is well-fitted, with no obvious off-gassing detected. The air inlet is located at the sides, while the air outlet is at the top to further distribute the filtered air. Being a pluggable device, it is very easy to use as there are no controls to tinker around with other than the USB port. Find a spot, plug it, and leave the UV sanitizer to do its things. Just make sure nothing is impeding the air ventilation of the device or close to flammable gases like fragrances and insecticides.

As for reliability and durability, GermGuardian GG1100 Elite UV-C Sanitizer comes with a standard 1-year limited warranty with US-based tech support. If there are any manufacturing defects, you can send them to many of the authorized service centers located in the United States.

GermGuardian GG1100 Filtration, Air Performance, And Noise

Let's be realistic in this part. GermGuardian GG1100 Elite is a pluggable, UV-C room air sanitizer designed for small rooms. The 56 square feet coverage is not outstanding, but it can still refresh your indoor air. Given its small dimension and budget-friendly price, the airflow output is adequate for most people that require clean, breathable air. No CADR is available as GermGuardian GG1100 does not fit the testing criteria.

For less than 50 dollars, GermGuardian GG1100 is a good filterless air purifier you can depend on. Powered by the single UV-C light technology with Titanium Dioxide to reduce volatile organic compounds and kills airborne viruses such as influenza, staph, and rhinovirus. UV-C light will also reduce the growth of germs and microorganisms such as fungi, bacteria, and viruses. It can also reduce light odors caused by mold, mildew, pets, cigarettes, food, and a diaper pail. While it is not in the same league as a HEPA air purifier, GermGuardian GG1100 air sanitizer works great in your office or home e.g. bedroom, kitchen, litter box, bathroom, children's room, and laundry room. You will breathe better, sleep better, and wake up fully recharged with it by your side.

As with all UV-light products, you should take extra caution when using one. Go through the instructional manual, as improper use can lead to cancer, birth defects, and reproductive harm. For California consumers, please read Proposition 65 before making a purchase.

Overall, GermGuardian GG1100 Elite UV-C Room Air Sanitizer is excellent in eradicating airborne bacteria and viruses within its area. It does not produce harmful byproducts like ozone that can irritate your lungs. The only thing you have to note is that the UV lamp life needs replacing every 10 to 12 months, depending on use. We recommend replacing the light bulb sooner than later as the germ-killing efficiency will drop after 3,000 hours of use.

GermGuardian GG1100 Pricing, Maintenance, And Drawbacks

Being a filterless UV-C Pluggable Air Sanitizer, GermGuardian GG1100 runs whisper-quiet as there is no gigantic motor fan. You can sleep soundly in the bedroom or place it in the baby's room next to the crib without having to worry about noise distraction. The 120 Volt AC, 60 Hertz power output is low, so it is safe to leave it running the whole day. The power usage is around the region of $0.4 per month or $4.8 annually with 24 hours of runtime. Your electricity bill will still look healthy even with multiple units of room air sanitizer. Very likely, you will not know its existence after some time.

At a fraction of its selling price, GermGuardian GG1100 Pluggable Air Purifier & Sanitizer can be yours for less than 50 bucks. It comes with a UV-C light bulb with a 5000 hours lifespan or an estimated 6-8 months for regular use. Replacing the light bulb will cost you 15-30 dollars annually, which is not too bad unless you have multiple units at home. Is it a direct replacement for a HEPA air purifier? No, but it can remove bacteria, viruses, and even foul odors without you ever lifting a finger.

GermGuardian GG1100 UVC Air Sanitizer and Deodorizer is well received by the public with overwhelmingly positive feedback. As long as you understand how a plug-in purifier works and its limitation, GermGuardian GG1100 Elite UVC Air Sanitizer would be a good buy to complement an existing air purifier.

What To Look For In GermGuardian Air Purifiers?

GermGuardian air purifiers may not be the most premium model, they will still bring clean, fresh air to your home, providing you choose the right model. To help you identify which is which, here are the features you need to consider when purchasing GermGuardian models.

  • Dimension and weight - Be mindful of the overall size. If you intend to place the air cleaner on the table, pick a device that is small enough to do so. Most GermGuardian air purifiers are designed to be compact, lightweight, and portable, apart from a few tower and console models.
  • Pricing - Not a major concern as most GermGuardian models are below the $200 price bracket. Instead, focus on the value the air purifier brings to the table.
  • Annual filter replacement cost - This is tricky as it varies from model to model. Smaller models tend to have lower filter costs, given the smaller filter size. As air purifiers will last for years, pick something you are comfortable maintaining on an annual basis.
  • Room size/ CADR - The most important feature in looking for a GermGuardian air purifier. Measure your room dimension and pick a model that has the suggested room size to support it. If you are asthmatic, divide the room coverage by 2 for a higher volume of 4 air changes per hour. If the recommended room size is unavailable, calculate using the Clean air delivery rate (CADR) figures provided by the manufacturer. The higher the ratings, the more airborne contaminants can be removed hourly.
  • Filter quality - GermGuardian air purifiers use different technology to clean the air. For most folks, choosing a mechanical HEPA with a carbon filter is the safest and most effective method. In some instances, a single UV light may work better to deal with pathogen infection. If budget permits, choose a certified True HEPA over a HEPA-type filter and an activated carbon filter over a carbon pre-filter. The more filtration, the more efficient particle removal.
  • Usability - Every little detail counts. Prioritize what you want, like noise level, autonomous operation, sleep mode, timer, child lock, and air quality indicator. If you can't live without it, get a model that comes with it.
  • Warranty and after-service - Varies between 1 to 5 years, depending on the price tag. GermGuardian air purifiers rarely break down anyway, so there's no need to put much thought into this.

Is GermGuardian Air Purifier Safe?

GermGuardian air purifiers are safe, as verified by AHAM and CARB. It uses the familiar air cleaning technology and mechanical HEPA filtration that you will find in every other model. Some model like AC5250PT comes with UV-C light + Titanium Dioxide that help kills germs through short wavelength radiation. The UV light bulb is safely contained inside the chamber of the air purifier, therefore preventing any risk of exposure.

Does The GermGuardian Emit Ozone?

GermGuardian air purifier does not emit ozone like an ozone generator. However, specific models that come with ionizers or UV light may release an insignificant amount of ozone byproducts that are neglectable. You can disable both functions if you are not comfortable using it.

How Do I Reset My GermGuardian Red Light?

Depending on the air purifier, some model like AC5600 comes with a dedicated "HEPA RESET" filter button that you can press and hold for 5 seconds to reset the filter indicator light. Models like AC9200 require a paper clip to press and hold the tiny button for 5 seconds after a successful filter replacement. Perform the filter reset when you notice a red/ blue blinking filter indicator light.

How Often Should I Change My GermGuardian Filter?

In general, GermGuardian air purifier filters should be replaced every 6 to 8 months, depending on indoor air quality and the hours of operation. Routine vacuuming on the pre-filter can help increase the filter's lifespan to a certain extent.

Are GermGuardian Air Purifiers Any Good?

GermGuardian is a reputable, dependable air purifier brand that can improve your indoor air quality. It comes in many shapes and forms, from the desktop, console, and tower air purifiers. The most expensive console air purifiers like AC9200WCA have high 200+ cfm CADR ratings for dust, pollen, and smoke; highly capable of removing small particles in the air. Most GermGuardian air purifiers also come with a multi-stage HEPA filtration to effectively capture airborne pollutants i.e. pet dander, pet hair, dust mites, mold, mildew, pollen, smoke residue, chemical, odors, bacteria, and viruses. Perfect for allergy sufferers that require absolute clean air to breathe every day.

How Long Does GermGuardian UV Light Last?

Depending on the light bulb size, most GermGuardian air purifiers and sanitizers UV-C bulbs need to be replaced every 5,000-10,000 hours or 10-12 months. The usage frequency and surrounding environment play a big part in the UV light lifespan.

Is It OK To Leave GermGuardian Air Purifier On All Night?

Yes, it is OK to do so. Not only should you leave a GermGuardian air purifier on all night, but it is also recommended to run it 24x7. The air purifier will constantly clean the air, making it safe to breathe. Airborne pollutants will fail to build up and contaminate indoor air when the GermGuardian is on. Do make sure the filters are replaced promptly to support the heavy usage.
