What buyers say about FilterBuy 18x30x1 Air Filter MERV 8, Pleated HVAC AC Furnace Filters
I needed replacement filters since my wife threw away the original one. I think they will do a better job of removing dust and other airborne particulate.
I know from previous experience that these filters are very good, and since I suffer from allergies, they are perfect.
These filters help filter out a lot of pollutants, and even air has a hard time getting through them.
I have ordered from them 3 times and they have been great with this product and supplier.
The product works as intended thanks to the great quick service andSolvusoft
Common Questions
I don't know how often I should replace it.
The manufacturer says 3 months with no problem, but I change mine every 2 months, which works out fine for me.
I measured my faf at 17 3/4" x 29 3/4", 1", is this 18x30x1 replacement that could be replaced with mine?
If it's too big it won't fit, as it's got a frame and can't be cut down to size.
What are the dimensions of the 18x30x1?
It's not a problem to put it in, because it's a bit less. Also, I began with Merv 11 but it was too dense for my a/c unit, 11 was more intended for a hospital.
What type of filter should be used to help eliminate smoking?
They don't eliminate odor filters.
Does this filter recommend the nordyne heating unit series m1b, m1g, m1m and m1s?
Measure your old filters and make a decision.
