Do I Need An Air Purifier? Are Air Purifier Worth It?

Believe it or not, these are the two common questions that we regularly receive (almost daily) in our emails. It might be a different scenario, location, or condition. The questions remain the same. Here at airfuji, we always say YES to an air cleaner as we are on a believer side (this is an air purifier site, after all). Still, there are times you might need to step back and think twice if a cleaner would make any difference at all. Don't just take it from me; I have stats and facts to back it up.
Short answer
Yes, air purifier does work and is worth it.

 

Do Air Purifiers Work?

YES, no question about it. An air purifier will capture airborne particles and smokes in a designated area. With fewer contaminants in the air, it will reduce asthma, sneezing, and other allergic reactions. Note that the keyword is AIRBORNE. Anything from dust, hair, to pet dander that falls to the ground will be Scot-free. There are few types of air purifiers in the market such as PCO cleaner, UVGI, and ionizer. Ignore all those and focus on HEPA air purifiers instead. It is the most common type that captures airborne particles onto its filter. You probably read this a thousand times; a true HEPA filter can capture 99.97% of the irritants as small as 0.3 microns.

So before we get to the juicy part, we need to make sure you are on the same page. You must BELIEVE in air purifier magic before anything else.

Do I Need an Air Purifier?

If you have extra cash to spare and want clean air, why not? Invest in a HEPA air purifier if you stay in an industrial area with bad AQI. Consider if you are a smoker, pet owner, or allergic to pretty much anything that floats. It will remove allergens like pollen, mold, and germs from causing any harm to our bodies. The same goes for tobacco smoke, chemical fume, and odors. If you are a smoker or someone in your group smoke, get it to suck in all the filthy chemicals, stat. That being said, if you are not suffering from any allergies or not staying in a polluted area, I’ll say skip it (for now).

There is no harm in having a GENUINE air cleaner whose sole purpose is to provide clean air. Some argue that an air purifier will burn a hole in one’s pocket on filter change and electricity bills. It’s true on the first part, as filter replacement will cost you even more than the machine in a few years’ time. As for the electricity bill, most modern air purifiers are Energy Star rated that run at the rate of a light bulb. Newer models are also intelligent enough to disable the motor fan when idle to save energy.

Is Air Purifier Worth It?

YES, but only if you could afford and maintain one. Invest in a HEPA air purifier if you stay in an industrial area with bad AQI. Consider if you are a smoker, pet owner, or allergic to pretty much anything that floats.

Most people overlook or make a mistake when choosing an air purifier. One should not assume an expensive air purifier is worth much more than a moderately priced model. There is no point placing a full-fledged model with super-wide coverage on a tiny room. A smaller, cheaper, and more energy-efficient air cleaner would also do the trick. To give you a clearer perspective, an RSP $249 Winix 5500-2 would not be too far off than a $749 Airmega 400 for bedroom use. Both come with autonomous purifying, Sleep mode, AQ indicator, and HEPA/ carbon filter.

Rather than going straight to an air cleaner, there are preventive measures that would improve indoor air quality without spending a dime. You could:

  • Start “fresh” and move out! Is not worth trading convenience over health in order to stay in a highly polluted area.
  • Vacuum regularly to reduce the number of dust and allergens at home.
  • Stop smoking indoor or better yet, quit smoking.
  • Improved room ventilation by opening more windows and doors.
  • Do the opposite by keeping everything shut during pollen season or hazy day.
  • Use range hood or exhaust fan to clear out cooking smell.
  • Speaking of smoke, any scented candles, fragrances or fireplace is a no go.
  • Chemical products usage like detergent, bleach, pesticide should be at kept at a minimal level.
  • Mold problem? Use dehumidifier to reduce humidity level in a room.

Air purifier is not vacuum cleaner

One more thing, an air purifier is not a substitute for your housekeeping work. Think more like a sidekick that traps disturbed particles from flowing back into your lungs. You will still need to vacuum/ mop thoroughly to get rid of ground dust and dirt. Keeping the purifying machine running in the background will also help reduce your cleaning frequency. Otherwise, an air purifier will only play a minor role that most would not appreciate its work.

6 Things to Consider Before Buying an Air Purifier

Even though an air purifier could do wonders to our indoor air, not everybody would need one. If you have poor indoor air quality due to internal factors, you need to get it fixed before anything else. Here are six checklists I would recommend you to go through even if you already have an air purifier at home.

Ensure Proper Ventilation

Opening more windows is an excellent way to start. For enclosed areas, include ventilator/ exhaust fans with a high humidity level. It will improve airflow plus remove moisture along with any bad odors. This method only works if outdoor air quality is good.

If There Is A Problem, Fix It

Have mildew problems in your water pipe? Fix it. Furnace system trapped with dirt? Fix it. Dampness and mold in your wall? You guessed it. Fix it. No air purifier in the world can prevent pollutants from building up from unreachable places. Whatever reason is causing the problem, locate the source and fix it. If fixing the problem might be complicated, seek professional help rather than let it drag on. Remember, the longer you delay it, the harder and costlier the fix will be.

Use Eco-friendly Household Products

Detergents emission are one of the primary sources of toxic fume. Check the ingredients in cleaning products and pick the one that uses fewer chemicals. If possible, use eco-friendly cleaning agents that are non-toxic to breathe in. A perfect example is the floor cleaners that you used. Avoid picking those with intense fragrance as the smell will evaporate into chemical fumes.

Schedule Cleaning

This want is a no-brainer. Clean and vacuum your house regularly. Store unused items in the storage compartment to prevent dust from building up. Carpets are notorious for trapping harmful particles like dust mites, pet dander, and dirt.

Limit Your Pet’s Activity Area

If you are one of the 10% of people allergic to pets, then I have bad news for you. You will have to keep your pet outside or limit their activity area, especially in the bedroom. Once pet dander gets stuck onto your upholstered furniture, it will be there unless there is a disturbance. You would not want to have a sneeze fest every day in your own home.

No Smoking Indoor

I saved the most common yet the most critical last, ban smoking indoors at all costs. You have probably seen ads, news, and even flyers brought back from your kids on the side effects of smoking. The toxic residues AKA third-hand smoke is beyond an air purifier realm. If you have to smoke, smoke outdoors.

Let's start with the most common statistics. Environmental Protection Agency (EPA) said indoor air quality could be up to 5 times worse than outdoor air pollution. According to the WHO 2002 report, indoor pollution is responsible for 2.7% of global diseases. In summer and fall, pollen counts are estimated 8 times more than other season. It significantly increases the pollen in-flow rate in our homes. Millions of people suffer from allergy symptoms triggered by indoor allergens. In 2017, 3,564 people died from asthma that is preventable with proper treatment and care (aafa).

Our in-house study shows air purifier will reduce 99% of surrounding contaminants within 48 hours of non-stop purifying*. However, less than 50% of the users would leave the air purifier on 24x7. Worst, ess than 10% of the users would replace their filter on time or when the filter is exhausted. 1 out of 10 purchasers think their air purifier did NOT improve their indoor air quality.

So what do all the numbers tell you? Indoor air quality threat is real and air purifier may not come to fruition.
