At the beachside house that I rent, one of the requirements is that the property manager supplies the air filters for the central heating and a/c plan unit.
I am not exactly fond of this because the air filters that they provide are awful. They are not even as nice as the cheap air filters I used to have for our old central heating and a/c unit. So what I do is just spend money to pay the small fee they have for their horrible air filters and write it off as part of our rent. Then I go out and get 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 the central heating and a/c unit! I always love to buy these air filters because when it comes to the HEPA brand, it is the absolute best. Not only can they last longer than official brand air filters, but they also work as an indoor air cleaner to a small extent. It is by no means the same as having a whole lake beach house air purification plan or even a portable air cleaner, but these HEPA brand air filters do a real great job in keeping the air quality of our beachside house that I rent at bay. This is as long as I keep up on the cleaning of the beachside house every single month. So that is how I get around and deal with the terrible air filters forced on myself and others by the property management supplier of the beachside house that I am currently renting. I look forward to moving later!
