    4 inch Filters
    prestondave  Wednesday, August 01, 2018

    I&#039 ve been purchasing 4 inch filters for some time. Fast Filters is FAST at very low cost. Their &#039 packaging&#039 for shipping leave a bit to be desired. Numerous times the filters arrived &#039 crushed&#039 on one end or the other from shipping. To their credit, they have responded by replacing the damaged filters.

    I ordered these filters, and about 4 days later, they were on my doorstep! They fit well, they filter the air well, and are an excellent value for what you pay.

    The filters are precisely sized, do an excellent filtering job and are long lasting. This is the second time I have ordered them from Filters Fast...

    I received my 3-pack of filters and they were just what i needed for my system at an afordable price which is about 1/2 of what i would have paid at lowes (the only big box store that carries that size filter in my town).
