Basically there are 3 types
- Fiberglass
- Pleated
- Permanente, washable.
Here are our recommendations
- I like pleated throw away. They are efficient and keep you system clean.
- Fiberglass (blue or white see through, cheapest) is ok but they allow some dirt to come through.
- Permanent, washable are ok but they restrict the air too much. Also they tend to not get cleaned as often because they take a lot more effort, having to get a hose and stuff.
- Three month filters are a scam! Think about it, if a filter works better, you will have to change it more often, not less often. This could only work if the filter is thicker than your standard 1”. Don’t waste your money at the big box orange store. Call me at 504.831.2000 and I will get you a better price on the best filters.
