At the house that I rent, one requirement is that the property management supplies the air filters for the central heating and air conditioning system unit.
I am not too fond of this because the air filters that they give are awful.
They are not even as good as the standard air filters I used to buy for my central heating and air conditioning system. So what I do is just pay the small fee they charge for their horrible air filters and write it off as part of my rent. Then I go out and buy the quality air filters that I want to buy. And the air filters that I do buy are the high quality HEPA air filters for my central heating and air conditioning system! I always like to buy these air filters because when it comes to HEPA, the brand is the absolute best. Not only can they last longer than regular brand air filters, but they also kind of work as an indoor air cleaner to a small extent. It is no means like having a whole home air purification system or even a portable air purification system, but these HEPA air filters do a real good job in keeping the indoor air quality of my home that I rent at bay. This is as long as I keep up on the cleaning of the house every single month. So that is how I get around and deal with the horrible air filters forced on me by the property management company of the house that I am currently renting. I look forward to moving later!
