I was originally buying a bulk pack of filters plus replacing them every 2 weeks.
When it came to buying things for my Heating plus Air Conditioning system, such as Heating plus Air Conditioning filters, I naturally leaned towards the cheaper options. And why wouldn’t I, they all looked the same to me. Even the HEPA air filters, which are supposed to be of great quality, didn’t look much odd to the generic stuff I was used to buying. However, not only were the air conditioning system filters I was buying poor for my oil furnace system, but they were costing myself and others more money in the end. This entire time I thought I was saving money, when I absolutely wasn’t. So, I ended up switching oil furnace filters, plus trying HEPA air filters. I chose those air filters not only because of their great quality, but because they can be washable. I’m not sure how well they work after being washed, but personally I haven’t noticed much of a difference in air quality or my air conditioning system component performance, so I believe it is okay. These are washable filters that can last a absolutely long time. I was originally buying a bulk pack of filters plus replacing them every 2 weeks. All I have to do is scrub the HEPA filters every now plus then, when they get dirty. I wish I had kept count of how much money I saved when I first started, but that was years ago, honestly I believe it could be in the hundreds by now. I would advise to anyone, try rewashable filters, they can save you a lot of money. I assume some people love the regular kind, but personally, washable filters are much better.
