One thing I observed is that occasionally when you buy the cheapest air filters for your central heating and air conditioner components that they are honestly pretty good! I bought some cheap and discounted air filters for my central heating and air conditioner component a few months ago and they honestly ended up being a close second runner up to the HEPA brand air filters in terms of quality and how long they lasted before they needed to be changed with new ones.
I was pretty shocked to be totally even-handed with you.
I was not expecting discounted cheap air filters to be this good! I was thinking that I would get it to where I had to change these once a month or there would be problems. But this was not the case at all. These cheaper air filters for my central heating and air conditioner component unit were honestly pretty impressive; then like I said, they were nearly as good as the unquestionably fancy HEPA brand air filters, but just fell short of the quality ever so slightly. I was not expecting this at all. So when they turned out to be so superb I went back to the store and bought a ton more of them and stocked up on them. I have been using nothing but these cheaper air filters ever since. So the thing is, never assume just because something is generic or cheap that it is going to be bad. That was not the case with these air filters for my heating and air conditioning component at all!
