14x24x1 (13.75x23.75) Air Conditioner Replacement Filters for HVAC/Furnace/AC Filters (MERV 8) (4-Pack)

To quote my Feedback for the Seller (Filters-Now)"Filters arrived quickly (5-6 bus. days) & appear to be just what the doctor ordered. They fit the bill in several important aspects, including the fact that: (1) they fit in the slotty whatsis on the furnace intake made for filters; & (2) the furnace has not blown up since they went in. These are the two of the most important qualities I look for in filters. The pricing is terrific as well. TY."(And man-oh-manischewitz, does Filters-Now have a warehouse-full of satisfied customers!: check out their feedback/ratings.)

Great performer at a great price. Fits like a glove. My contractor suggested that it would be better overall to replace an inexpensive and lower MERV rated filter more often, than to try and stretch out a more expensive and higher MERV rated filter by keeping it in there longer. So Im followed his advice and bought these in bulk. So far so good.

These air filters that go into your vent returns did the job there are supposed to do. They fit in easily and I guess there are filtering the airflow.

Air flow seems to be good. System doesn't seem to be stressing and filter appears to be grabbing dust.

Installed two of these in my house and in one return vent, the filter has a whistling sound. I replaced the filter with another new one and it still whistled. I put 1/4 foam in the frame that the filter sits in, tape around the edges of the filter, and more tape on filter but nothing seemed to help. The whistling is from the pleated filter not the edges. It may be my return creates such suction but it didn't whistle before with filter installed with the house. I will try another brand next time.

the Product work fine. I will buy more in the future

Work great. I could use the free ones that the building mainly. offers, but I'm trying to filter air, not bowling balls. These economically filter air thank you!

Good
