Get the Best Performance From Your HEPA

There are lots and lots of personal air purifiers for sale out there. So, make a great buying decision by using a little knowledge.

It is not beneficial to add ozone to your indoor air. Ozone is a reactive and unstable molecule that may disrupt airborne bacteria. That’s why some believe it should be added to air purifiers. Bacteria is everywhere. Ozone is not selective and kills both good and bad bacteria. So, let’s not kill the bacteria with “activated oxygen” as some air purifier manufacturers advertise. And the environment definitely has enough ozone – we don’t need to make any more.

Insist on paper or paper with carbon/charcoal filters only. Do not ever reuse washed, plastic HEPA filters. Here’s why: the dust is trapped in the folds. Moisture gets trapped when the filter is washed. The water feeds the mold. Then, when you replace it in the unit and turn it on, mold spore counts in the breathing zone go ‘way up. Keep yourself safe: buy paper only. Charcoal/carbon is used to remove vapors (odors) and is useful without adding a bunch of “stuff” in the air.

Buy the right sized machine to clean the air in your room. What I do is turn my old Honeywell on HI during the day (it’s loud) when I don’t use my bedroom. During the night I move the HEPA to my office, again on HI. I’m writing this post during the worst air pollution San Francisco has ever known from the fires in Northern California. I have maintained particulate levels for 2.5 under 25 with outdoor levels over 300.

Here’s a GREAT article from Consumer Reports.

There are better air purifiers offered for sale than those sold by a lot of MLM companies.
