“These are pricey filters and are not fully true HEPA. True HEPA would probably restrict airflow through a whole house HVAC filter system. They are also a bit difficult to get on the guide tracks to the Aprilaire system. I also wonder if a washable prescreen couldn't add life to the filters. The manufacturer might not want this, however as it would cut into the sales of the replacements.”
“Great price point and VERY fast delivery for OEM product. With virus going on I was unable to purchase locally due to plumbingsupplyandmore being closed. Thanks plumbingsupplyandmore for getting me the filters I needed!”
“Been buying these for the last year and just put a new one in for the winter.Saves me money.Been buying these for sometime this is the (7)time and this time the box was ripped because it was not in another box.It was ripped and spending over 40.00 for it.It should be box right!!!”
“Filter mounting channels rack are a little tricky mounting on support rack, because there are four of them which have to be attached simultaneously, two on top and two on bottom. I found installing the two on the bottom first and only pushing them in about one or two inches first and then the two on the top worked best. Collection efficiency is as promised. We have dogs and cats, so 6 mo. replacement schedule seems to work best for us to prevent drag-thru of contaminants.”
“I've ordered and used these filters for years. Will continue to purchase. They arrive in the box that perfectly fits the filter. I totally get this, but in my case the box was damaged and the bottom flap was open so the filter was already dirty. I returned for another. This one was fine, but came damp bc it was a rainy day. The cardboard is not very thick. I would suggest a plastic covering be added to boxes before mailing to ensure they are received in better shape.”
