Mold Poisoning Symptoms and Health Effects

Mold poisoning can be a serious health issue when not handle with proper care. One might experience mild symptoms like flu, sinus, watery eyes that are hard to call if is mold-related. Other more serious symptoms include asthma, eczema, migraine, chronic cough, nausea, and diarrhea. Pro-long exposure to mold toxic can lead to many types of respiratory and liver failure. It can also reduce eye sights, reproductive capability, mental disorder, and neurological damage. It’s always better to be safe than sorry with Mold.

How do we measure?
Pollen CADR Regardless if the allergens are mold, pollen or mildew, the higher pollen CADR scores, the better it is. Measured in CFM (cubic feet per minute) on the amount of clean air that flows out of the air purifier. We pick Pollen CADR as a key point because it is an industry standard measurement by AHAM. Not all brand participate in the CADR test so HEPA filter is perhaps an even higher measuring factor.
HEPA filter Pollen, mold and mildew are all microscopic allergens that is hard to be seen through our naked eyes. Only a HEPA filter would have the capacity to get rid of these microbe irritants. Not just any HEPA filter, a genuine True HEPA filter is precisely what we are looking for. To be part of the list, there must be a HEPA filter capable of removing microscopic allergens. Bonus points will be given to the HEPA air purifier that plays well with other filtration.
Room size/ Coverage Never underestimate the speed of mold and pollen infestation. Mold can spread around the house within 24 – 48 hours and slowly colonizes your home space one inch per day. Pollen is no slouch either that spread into our breathing space rapidly as it’s mostly airborne. An air purifier with strong airflow can easily cover an entire room from allergens intrusion. The wider the purifying coverage, the bigger room size it can support. But that cannot be the sole factor in determining the best mold air purifier. We also judge the air purifier based on its size, category, airflow speed and the cost of ownership.

Who is this for?

First, people that have been diagnosed with mold allergies by an allergist. Second, a person that is allergic to pollen with seasonal symptoms as above. Third, staying close to nature, has lots of tree/ plant and open windows all the time. Fourth, an asthmatic person that is at higher risk in triggering an asthma attack. Fifth, children or elderly people with impair immune system. Lastly, anyone that needs clean air throughout the day free from pesky pollen, mold, and mildew.

Technically any of the Blueair air purifiers would fit into our best air purifier for mold spores list. We pick Blueair 605 because it is the most powerful in its Classic lineup. Mold, spores, and other allergens would have to go through a series of filtration so absolutely no chance of them sneaking out.

What's cool: The same HEPA Silent Technology that works like a charm against the finest particles. Crazy high 640 cfm pollen CADR. Also best room size purifying coverage in its classic series at 775 sq. ft.

What's not: Expensive to own and maintain. Bulky and heavy. Does not fit well in constraint spaces. Auto mode requires add-on monitor purchase.

In short: Powerful air purifier that will cost you an arm and a leg. Blueair 605 does have its fair share of downside and is "gigantic" literally. Depending on your purifying needs and how serious is your pollen allergies is. You could opt for the smaller version in Blueair series that gain the benefits of reduced body and price.

Do not be fool by Rabbit MinusA2 SPA-780A so-called “average” pollen CADR output. This is the ultimate 6-stage mold eliminator you can get your hands to. It has excellent purifying coverage (815 sq. ft. to be exact) that is ideal for any bedroom size.

What's cool: 6-stage filtration including pre-filter, medium, HEPA, carbon, and negative ion generator. Add-on Germ Defense customized filter to get rid of stubborn mold, pollen, and mildew. All the bells and whistle you could think of.

What's not: You will have to pay top dollar for this air purifier. The Germ Defense customized filter add-on is an extra cost.

In short: In spite of MinusA2 and compactness and nifty purification, everything else is costly. This is arguably the least favorable price per airflow ratio model. If you could do with a smaller purifying, downgrade to the cheaper but identical MinusA2 SPA-700A.

Many sites did not include IQAir HealthPro Plus in their "Best air purifier for mold list". Why? Because it is not an affiliate selling model worthy (psst is expensive). Not us as the airflow performance and filtration alone justified the inclusion. Top it off with a leading 6-speed mode and super wide coverage, you can never go wrong with HealthPro Plus.

What's cool: Remarkable HyperHEPA filter that trap allergens as small as 0.003 microns. Way smaller than any household mold, pollen or germs ever existed. The latest version comes with 25% more clean air, 32% more silent. and 38% longer filter lifespan.

What's not: Again, pricing is the main reason. Filter's sustainability is another. The lack of features like Auto mode, air quality indicator is the biggest downer.

In short: The best mold removal machine when money is no biggie. If you have the budget and can sustain its yearly filter replacement, go right ahead. Otherwise, consider the next option if you want an air purifier that is more feature oriented.

Winix HR1000 is another popular air purifier for mold that breaches the premium line but at the lower end. Let's put it this way, it cost close to double of Winix 5500-2 but only half of Airmega 300. Regardless of the price, this is a very good air purifier for all-purpose.

What's cool: 5-stage HEPA filtration including antimicrobial that stop mold from growth. High 301 cfm pollen CADR output that exceeded our requirement. 400 square feet coverage is more than enough for most folks. Equipment wise, Wi-Fi enabled, timer, remote control, Auto/ Sleep mode all checked.

What's not: Around $100 for filter pack is not a lot in air purifier world but keep in mind it is a yearly recurring fees.

In short: If you need a dependable, 5-stage filtration air purifier that is easy to use, HR1000 it is. Sure the filter set is expensive, but it comes with both HEPA + carbon filter and more importantly, it works! If you could save 1 dollar a day, it will only take 100 days and you have a whole year time frame to do that.

Most Winix air purifiers would fit well in our best air purifier for mold/ pollen list. We pick Winix NK105 out of the bunch as it is the only tower air purifier here. It’s considerably cheaper compared with the above air purifiers and is ideal for medium room size.

What's cool: Respectable pollen CADR and airflow delivery rate. Highly dependable True-HEPA filter with PlasmaWave technology. Adding timer and Wi-Fi enabled feats, you have yourself a superb mold removal machine.

What's not: Pairing the air purifier and phone is a chore but thankfully you only have to do it once. Filter cartridge is expensive to replace and has to be done annually. The bright indicator is a bit of nuisance.

In short: Winix NK105 strike a balance between price, performance and overall dimension. On the flip side, It's not the smallest, cheapest and most silent mold air purifier in the market. If you could leave out the Wi-Fi feature that brings nothing in allergens removal, go with NK100.

Need something a little bit more affordable in dealing with mold? Again and again, Honeywell HPA300 allergen remover is your answer. It might not have an outstanding exterior or jam-packed features, the remarkable performance will make up for all.

What's cool: Impressive 465 sq. ft. coverage. that can cover a lot of ground. 300 cfm pollen CADR is no slouch either. Pricing is on the friendlier side too.

What's not: Plain on features thus no Auto mode, Sleep mode, AQ indicator, or remote control. Filter replacement cost is on the high side.

In short: A great mold air purifier that is dated on features. If you do not mind the manual control and lack of night mode, this will do just fine. If the filter cost is too much of a burden, consider the smaller HPA200 or HPA100 air cleaner.

Rather than pushing Airmega 300, let's go with the higher spec model. There are lots of things to like about Airmega 400 as a mold air purifier that we could go on all day. You only need to know that it is a proven, reliable, and effective pollen/ mold killing machine.

What's cool: A whopping 350 cfm pollen CADR with 1560 sq. ft. coverage. Relies purely on mechanical filtration setup (dual pre-filter + HEPA and carbon filter). Timer, Auto/ Sleep/ Eco mode with air quality indicator all comes standard.

What's not: The price tag for one. Follow by the filter maintenance that requires annual replacement. No ionizer in the filtration but it's not a big miss.

In short: Yet another expensive air purifier that not meant for everyone. Unless you have plenty of cash to throw around, it might be better to hire a mold expert to fix the problem. With the leftover cash, get a cheaper HEPA air purifier.
