Microsponge has the highest efficiency and the lowest pressure drop of any charged media in the world.

I have been using these filters for over 5 years now, and I can only say that there are no better filters on the market than these filters!!! Every time I have my unit checked the tech wants to know where I get my filters, as he says he has never seen any better filters than the ones I have, and that I should never stop using them, as I will keep my unit a lot longer using these filters!!!

Review of Filters
We have purchased filters for our cold air return ducts for 15 years due to allergies in our family. We have regularly replaced them every 3 months and each time have been amazed by the amount of particles trapped by each filter. My wife agrees that without these filters she would be much worse. They seem to work effectively and are simple to install and change. We would prefer them to be less expensive, but that is the only less than positive statement one can make.

Great Filters
Online ordering is simple and I received my filters in 3 days. The filter collects a lot of dust and I imagine the tiniest particles. I have been very happy with the filters over the years.

Great filter and good customer service
I just got and installed my refill of the micro sponge filter. I found FilterFactory online a couple years ago when I first needed replacement filters. Both the first and the second orders were handled expeditiously and politely. They definitely reduce odors and dust, and I recommend them!

Allergies and Health Issues in Our Home
Don't hesitate. We have been buying these custom fit filters for over 14 years! We have numerous allergies and serious health issues in our home. Also elderly family,with chronic breathing issues, who visit. Also, I dislike dusting with a passion. These filters dramatically reduce the need to dust often. You won't regret ordering these for yourself and your family.

Just received my third re-order and I could hardly wait because I procrastinated and there was dust everywhere. Now I can breathe. Custom frame with perfect fit and very efficient filters. Quick response to my order and equally fast delivery, even though most of Florida was under water. I hope that you did not suffer damage or loss and that more people learn about your great products.. There are no off-the-shelf filters available and our apartment custodians replace everyone else's filters with misfits that allow dusty air to bypass the change-every-month filters.

misleading
I received my Micro Sponge 4x pack today. your website states that there is 4 refills to a pack. so when I purchased this item that says 4 pack, one years supply. I was surprised to only find 4 refills in total and not 4packs of 4 micro-sponges filters for one years supply totaling 16 micro-sponges filters . as air-conditioning manufactures recommend you change your filter monthly 4 filters is not sufficient. So I seem to be short of 3 Packs? thank you for forwarding me the other 3 packs.

Mr
My wife and I have medical issues that make it a necessity to find and use the highest quality air filtering systems available for both of our A/C units. Air Sponge fits our needs perfectly. The quality is excellent and consistent with every delivery. We have used the Micro Sponge for many years are very pleased with the product. We highly recommend this product to anyone concerned with the quality of air they breath.

The MicroSponge filters are very efficient. The Filter Factory's reminder system and mail service makes keeping clean filters installed easy. The company that does routine maintenance on our heat/AC system is impressed with MicroSponge and told us he'd ordered some for his home.

MicroSponge Filters
I have used microsponge Filter for the past 4-years, with extremely good results. My wife also declares there is a noticeably reduction of dust on furniture and entire house. She is a clean freak so I take her judgment serious. Therefor I keep a years (4) supply.

Works very well
I have been using this filter for at least a few years and they were one of the only companies that could make the filter that I needed and the design and performance have exceeded my expectation. I started with the big guys filters and the price/performance of this product do better than the other guys.

This is our second year ordering these filters. They are easy to use. Because there is no cardboard frame, the are easy to keep stored in the box in a small space. Thanks for a great product.

Excellence in design and function
As an orthopedic surgeon with a wife who is severely both asthmatic and hypersensitive to most airborne odors, physical and chemical airborne contaminants and who had progressive COPD, I am understandably very concerned about the quality of the air filtration of our HVAC system. I have been using the Filter Factory microsponge filter system for some time now. I recently switched from the hinged frame to the magnetic snap frame to hold our microsponge filters in our HVAC system and find the snap frame easier for me to use. We have found no filtration system that can begin to compare to the microsponge system along with the Zeolite pad to remove VOC's. And with an odd sized filter frame requirement there was no other available filter system that could compare. Other companies may say they make custom sized filters But my personal experience is that these are lesser quality pleated filters in weak cardboard frames with two or more filters taped together with masking tape and which often collapse when subjected to the suction of the furnace blower. The Filter Factory custom aluminum frame forms an airtight seal with its rubber gasket and the filters work better than any of the many products on the market that we tried in years past to reduce dust along with physical and chemical contaminants in our home. Best investment you can make if you want clean air in your home for yourself and your family. I consider the cost a bargain for what we get.

Custorme Service Review
I debated for some time whether or not I should tell you about my experience with your customer service when I was trying to complete our last order made June 5, 2013. Before I tell you that I do want to say we love the product and are so thankful we were able to have the frame made several years ago to accommodate the filters. We had tried everywhere to get something that would work, even through contractors with no luck. So thank you so much. The day I called customer service June 5th, I was trying to complete my order and was having a hard time with the "check out procedure" on the internet. It kept telling me my credit card was not accepted...the only credit card I ever use online. After multiple tries with no luck I called customer service to order over the phone. I encountered the most rude and unhelpful young woman I have ever encountered on the phone in all my 70+ years. I realize I was frustrated, not with her but with the process, and she kept accusing me of yelling at her and told me to calm down, etc., etc. She kept telling me it wasn't her fault I couldn't figure it out and that I couldn't order on line. Finally I just hung up and paid for the order through PayPal with no problem at all (using the same card). If we had any place to buy filters that would fit the frame your company made I would never order through your company again. I for sure won't call customer service. Rating for the filters is a 5, customer service 0. I don't expect you to post this review but felt you should know. Carmen Todd

Excellent product
I have been ordering the Air Sponge filters for some time now and never have I been disappointed in the product. It is of excellent quality and performs the job it was designed to do without fail. I depend on these filters to really clean the air because I have allergies. I don't think anything gets through these filters. They are truly like sponges that catch everything in the air in your home.

Love this product! Best filter on the market. We have been using the MicroSponge for approximately 9 years. Have tried a couple of others in between...due to moving and different furnace/air system...but we always come back to MicroSponge!
