Seems to have only a few less pleats as a 1900 limited info out there on these but I'm glad to have a budget option that seems to perform well and let's the HVAC unit breather easier. More pleats equal better air flow and less static pressure for your system when it starts to get dirty. Less stress on HVAC units

Filtrete is a very good filter. Traps the pollen this time of year. I have a dual heat pump that has different Returns and the settings. One upstairs and one downstairs in the ceiling. I also have a larger return in the Den. All work well with Filtrete filters. Rarely have to dust!

Great brand, great filter, great price.

Really good filters! Much better than those 'rock catchers' I had been using.

Excelente calidad a la medida exacta

Perfect fit! Not everyone carries the 20x30. Great price for 4.

I have used these filters for years. These filters are the only ones I buy for my central air.

Great price, great product

These are very good filters

Always buy these on sale at Sam’s Club. Good value.
