I got a cheap tower Holmes from Walmart for not that much (less than $100) and I put 2 99.99% filtration HEPA filters in it and have been running at half speed most of the day for over a year. I shake out the pre-filter (gets covered in dust and pet dander) and toss out the filters every ~6 months. I use a filtrate 1900 filter for the home air filter. Tip: never use the "ionic" button. They come on most filters for some bizarre reason, but ionically charging the air is a bad idea.

“ ionically charging the air is a bad idea.” Why?
- r00fus 5y ago
  Ionic means ozone generation. The idea with charged filtration is that microbic particles are attracted to the filter. However, ozone is a lung irritant.

    > Ionic means ozone No it doesn’t. Who told you that? Ozone generators are a completely different thing and air ionizers must conform to low ozone emission standards.

Among others, the EPA [0]. > Ozone generators are a completely different thing They are, but ionizing air cleaners still generate ozone even though they are different than “ozone generators”. [0, again] > and air ionizers must conform to low ozone emission standards. No, only the small minority that claim health benefits in a manner which brings them under FDA medical device regulatory authority do. [0, again.] But even those so regulated in ozone emissions are net ozone generators.
