Seems to do the job

I keep purchasing this brand & model. Always exceeds what it is described as. Will continue to purchase this item when need be. Shipping was quick. Easy installation!

Standards for filters do not exist

Apparently doesn’t fit any 20x20x4. Why can these filters be labeled some standard size but never reflect what they really fit. $40 wasted. I should have burned 2 x $20 bills in the backyard. Would have been more efficient. You stole from me Filtrete.

Great product, great service.

We love these healthy living filters purchased from sylvane. Living in Texas we have every allergen under the sun and using these filters as one way to protect our home from the allergens brings some relief. Order was easy to place and came quick! No complaints at all.

Too heavy, furnace malfunctioned as a result.

This is probably a good air filter but Sylvane's product info does not give any instruction or advice on selecting a filter based on how much air flow will be restricted. This filter is so dense that it caused my forced air system to malfunction because it could not push air through it.

Filter keeps the air clean within your home

Have been using this air filter for some time in my home heat/air-conditioner system. Was recommended by my local service agent and does an excellent job picking up particulates. It replaced the electrostatic wire filters which were not getting the job done. I have been very pleased the performance with this filter.

Great filter but why did the price double within the last few weeks?!

This is a great filter. I've been using this brand for many years. I bought this from Target(.)com three weeks ago and it was $29.99. I came back today to buy another one and the price is $63.99!!! What the heck happened?! I will not be purchasing.

Air filter

I couldn’t rate the filters at this time as it is the first time to use this brand. 1 star is because I had to choose a rating
