AIR PURIFIERS FAQ

What causes indoor air pollution?

Modern homes are sealed tightly, it is bad for your allergies. Those tight seals trap all kinds of contaminants in your home. Pollutants like tobacco smoke, pollen, mold, dust, and animal dander can cause asthmatic and allergic reactions, making homes unpleasant and unhealthy for allergy and asthma sufferers. Other contaminants, like chemically reactive gases and VOCs, can cause allergic reactions with some being carcinogenic and/or toxic.

How loud are air purifiers?

Some air purifiers are extremely quiet, while nearly all can be quite loud when operating at high power. If possible, ask for a demonstration before you buy your air purifier, and for the majority of air purifiers we offer, there are decibel ratings on the individual pages.

How do I know when to replace the filter(s)?

Luckily, you can take the hassle out of filter replacements by joining the Clean Air Club, our free filter replacement reminder program. Well do all the work for you and automatically remind you when its time to replace your filter(s). Otherwise, some air purifiers will have integrated timers that will alert you when a set period of time has passed (coinciding with the manufacturers suggested replacement schedule). A few air purifiers will provide more specific replacement times by calculating the total time the machine has been operating vs. the the fan speed and determining when the filter needs to be replaced based on that.

How often do I need to replace the air filter(s)?

If you are buying a HEPA air purifier, don't forget to check and see how much replacement filters will cost. If your unit includes both a HEPA filter and a carbon filter, or other combinations of filtration media, they will probably need to be replaced separately, and they may last for different periods of time. Typically, HEPA filters can last anywhere from six months to five years. These times will vary according to the air filter manufactures, the total surface area of the HEPA filter media, and the conditions in which you operate your HEPA air purifier.

Should I run my air purifier all the time?

We recommend that you run your air purifier continuously for optimum operation. If noise is a consideration, we generally recommend running it at higher speeds while away for work then turning the fan speed down to quieter levels before bedtime or when you get home.

Will the air purifier clean the air for my whole house?

No, a single air purifier will not clean the air in your entire house. Even whole house systems can have a difficult time effectively cleaning the air in your entire house. Whole home units with HEPA or near HEPA filtration are possible solutions, but be mindful of the pressure drop after the filters. Air is pushed throughout the home by a blower and dense HEPA filters can significantly lower airflow.

Where should I put my air purifier?

If you suffer from allergies, then the best place for an air purifier is your bedroom. It is essential to have clean air in your bedroom because you spend about a third of your life there. If you'e allergic to animal dander and have pets, then you may want to place an air purifier in the room where your pets spend most of their time and keep the pets out of your bedroom! Also, you should not place an air purifier in the corner of a room; it should be at least a couple of feet away from the walls for maximum air flow.

There are many factors to consider when shopping for an air purifier, but two primary factors to consider are the type of pollution which you are trying to eliminate and the size of the room the air purifier will be used in. And, of course, the performance of air filters.
