    washable hogshair vs disposable fiberglass

    Which has a higher MERV rating?

    Saw a washable hogshair filter that claimed MERV 4 (would not have thought it was that high) and was wondering if washable hogshair provided more filtration than disposable fiberglass which does not give a MERV.

    both are poor filters!
    strive to get to 4inch thick pleated = getting ducts to proper performance levels

    fiberglass probably= 2 MERV

    better change/ wash ea 2 weeks
    if coated, too long between maintenance events
    harvest rainwater,make SHADE,R75/50/30= roof/wall/floor, use HVAC mastic,caulk all wall seams!

    if you can sprinkle salt on a filter and it can pass through it you dont wont it.

    I use NaturalAire Standard pleated filters, MERV 8, made by Flanders. A 3-pack from Home Depot is $7.

    Good luck.

    Hogshair works great for large particulate like over-spray in paint booths. Fiberglass has a slightly higher merv rating but has a lower holding capacity than hogshair. Even a "cheapo" pleated fiflter does a better job for your application.
