What To Consider When Picking Bissell Air400 Air Purifier

Real HEPA filter

It is important to understand what a HEPA filter is because basically all such products come with it. With something like this, your air purifier will be able to capture about 99.97% of particles as small as 0.3 microns. Just imagine what the fresh air you will breathe. We would recommend that you replace this filter every six months or so.


This is an important feature of all air purifiers with HEPA style filters. Usually, the pre-filter catches pet dander and a lot of dust. They can also extend the lifetime of the primary filter used by the device. The good news is that most pre-filters are reusable and washable. If you take care of them, they may last a lifetime.

Activated carbon filterc

If your house often smells of smoke, food, chemicals, etc. You must need to look for equipment equipped with activated carbon filters. This type of filter can absorb gas and odor particles.

ACH / Number of air changes per hour

This ACH number shows you how many times per hour the air in the defined space is changed.

CADR / Clean Air Delivery Rate

It is important to know what CADR is because the ratio actually measures the efficiency of the air purifier. CADR takes into account the size of the room and the amount of clean air produced per minute. CADR is a standard rating developed by the Independent Association of Household Appliance Manufacturers (AHAM), which evaluates the removal rate of pollen, dust and smoke (the three most common indoor air pollutants).

You need to look for an air purifier with higher CADR allergy, because the higher the rating, the better the air purifier.
