AIr Purifiers - do they work?

Does anyone have any feedback on air purifiers and their ability to actually clean the air and smell/feel the difference in air quality?

I read that it can remove mold spores just as well...not that I have a mold issue, but mold being small as they can be, are these purifiers that effective?

Not all filters are made the same. Look into "true" HEPA air purifers.

Yes they are, be sure to read the reviews before you purchase. Make sure the Sq Ft coverage, doesn't make sense to buy a small purifier for a large living room.
Yes, you can feel the air much cleaner after purifying.

By the way, I got the Germ Guardian 3in1 with HEPA filter 28in. Cost like 130 on Amazon. Has 3 settings L / M / H and ION light filter.

There's also the Filterless models such as those from HoneyWell Air Genius...they don't use HEPA though, but suppose to be better....

We have two Air Rabbit Air Purifiers, one for the bedroom and one for the living room. We have seasonal allergies and two cats, literally every week I vacuum a thick layer of dust, hair and stuff that gets into the filter and prefilters.

It definitely helps a lot.

Air purifiers do work. They remove contaminants, both macroscopic and microscopic from air. This can be shown via evidence:

https://thewirecutter.com/reviews/best-air-purifier/

In that article, the staff uses particulate sensors to show how much tiny particulate matter is in the air, both before and after purification.

The question, though, is 'do you need air to be that clean'? If you have allergies to dust, pollen, or other particles often found indoors, then sure, it can help. If you have asthma and find that ultra-clean air helps, then sure. If you have poor household hygiene and don't vacuum regularly, then sure, it'll help. If you have pets, then sure, it can help, since they spray dirt, dried saliva, dried hair, skin flakes and bits of hair into the air. Some air purifiers can also address VOCs, which can come from cleaning supplies, new paint, etc. They catch mold spores, and sometimes bacteria and even viruses.

The thing is, our bodies can typically handle a bit of dust and dirt. Our lungs have quite effective self-cleaning systems. We are, after all, evolved to live in the great outdoors where there is plenty of dust. We also have furnace filters which will catch a lot of the gunk. There is also a risk for some of having a home that's 'too clean' - the hygiene hypothesis implies that, due to extreme, unnatural cleanliness, the rate of allergies and autoimmune disorders is on the rise.

I'd say that if you don't have an issue with dust, don't own pets, and don't suffer from particulate-related allergies or other conditions, then don't bother.

I don’t know if only one unit in the bedroom would help, but with other units throughout the house, it’s been a world of difference. We’ve even noticed less dust in the house.
