Air Purifier guide

Best home air purifier. Guide to chose the purifier for you

You have decided that air quality is an important factor in your life. You tested the air as we talk in the post about air quality testing. Also, you checked the air quality index and it is not looking so good in the region. What to do next? A solution in these situations is an air purifier. They are electronic equipment that helps reduce pollutants from the air inside the home. In the following post, we will talk about the best home air purifier using different criteria.

There are two types of purifying technologies, active and passive. Active purification means the equipment is releasing negative charged ions into the atmosphere. Due to this, pollutants get stick to surfaces. Passive purification means the equipment uses filters to clean the air. Out of the two, passive technology is more efficient and doesn’t release any pollution with ozone into the room, as the active ones do. There is an industry-standard that requests a maximum of 0.05 PPM which is not dangerous for your health if you decide on an active one.

A disadvantage of passive technology is the fans used to move the air into the filters making them more nosy than some active technologies that do not use any fans. Also, there is the effort of changing periodically the filters.

There also is a category of purifiers that intentionally emits ozone. This equipment is used to take especially strong smells. It is often used to clean crime scenes of a strong decay smell. This technology is very dangerous due to the high amount of ozone release, over 3000 ppm, so home use is not really recommended.

In conclusion, even with the effort of changing the filters, we recommend the passive technology. It is more efficient and non-polluting.

The best home air purifier

If you have decided on a passive air purifier then it is important to talk about filtration. The best filter is HEPA, high-efficiency particulate arrestance. This filter removes 99.97% of the 0.3 microparticles. Usually, the HEPA filter follows an easy to clean pre-filter. The role of the pre-filter is to remove bigger particles so the HEPA filter will last longer.

In conclusion, our best choice is the Honeywell HPA series True HEPA Air Purifier.
