Review on Holmes AER1 Total Filter HAPF30AT by Sean Garrison

I bought a Holmes air purifier for my bedside table a long time ago. I started buying filters from Revain because they are always available (not like Walmart) and if I buy them with a subscription they are cheaper. I know the filter is removing dust and allergens from the air because I can see it go from bright white to brown and brown over four months of its life. I also sleep better throughout the night with this run, not only because I'm breathing cleaner air, but the white noise of the fan lulls me into a deep sleep. (I live in an apartment building and this blocks out the noise from the incel boys on the balcony across from my bedroom window who smoke and smoke all night and also cough and huff.)
