The Ultimate Buying Process For The Best Air Purifier for Allergies

The best air purifiers for allergies give you cleaner air because they have a highly efficient filter to catch airborne particles. Also, you should consider some main features when buying this device. Here they are:

1. Filters

High-performance filters will protect your family’s health for a long time. It will remove abundant pollen, dust pollen, and even dust mites. Also, it can capture the small particles in the air to prevent you from suffering from allergies.

If you own a pet, the pet scales and simple mold spores move around. Even if you clean the room every day, it is difficult to remove these small seeds. Therefore, equipping a home air purifier is essential.

In terms of filters, HEPA filters remove 99.99% of dust or more particles of 0.3 microns that you may be allergic to. Besides, HEPA-type filters have lower performance because they are not genuine HEPA filters. This type of filter only removes large pet scales and cannot catch the smallest particles you may inhale.

One tip here for you is that you can buy pre-filters to remove the bigger-sized things like pet hair and dander. The pre-filter supports the HEPA filter, so it doesn’t clog with these particles to reduce airflow and damage the whole device.

2. Delivery Rate

The next thing you need to check is good airflow through air filters. This feature is known as the clean air delivery rate – CADR. What is it?

It tells you how much clean air comes out of the air purifier in a specific area.

The Association of Home Appliance Manufacturers (AHAM) designates CADR to measure the efficiency of filters. It shows how good air purifiers remove smoke, pollen and dust particles (10-450 CADR for smoke, 10-400 CADR for dust, and 25-450 CADR for pollen).

Note that your air purifier can quickly filter once  the CADR for each type of pollutant is high enough . You can learn more about the CADR rating scale here.

3. Room Size

If you want to choose an air purifier for a specific room area, please take a look at the following example:

Imagine that you want to have an air purifier for your 400-square-feet living room. And you have an 8-feet ceiling, and then your place has 3,200 cubic feet.

With the air from the ventilation system or the open door, the air purification system must filter a lot of air throughout the entire house.

Generally, to maintain high air quality levels, you should change the air 4-5 times per hour for room air purifiers. In other words, you need 12,800 ft of airflow per hour (3,200 x 4).

Now, we continue to convert the room size into CADR by taking the above result divided by 60. Finally, you should choose at least 213.3 cfm of CADR ratings. (12800/60).

It’s your turn to calculate and buy suitable air purifiers for your own house.

4. Noise Level
