    I ordered 2 filters & received them the net day. It was almost half the price of what the contractor we bought the air cleaner from quoted me. I found a video on Utube that explained the process of installing it. Everything is working great!

    Ordered two replacement units because of the discountand they arrived quickly. Replacing the media for the first time went well and instructions seemed quite clear. Having said that it indicated rotating the seperators but I believe snapping them out is a more appropriate instruction

    Bought two to have a replacement on-hand when needed. Appreciated the volume discount, and prompt delivery.

    #501 media for our Aprilaire air cleaner was easy to install with directions on box. Cost was less than our furnace contractor/installer was going to charge. We have ordered on line for 2 years, and appreciate the good service.

  • Thanks

    Great service - ordering direct from Aprilaire saves me at least 45% for filters as opposed to my service provider (even with shipping).

  • Delivery arrived in record time. Thanks.

  • Great Service

    Posted by: Casey


    I always order my filters direct from Aprilaire. Genuine part is guaranteed. There's always some discount for ordering more than one, and shipping has always been free. It makes sense to get them from the source. Our house is practically dust free, so the filter system is obviously highly effective.

  • Easy Installation

    Posted by: Ryon


    I was worried if this would be over complicated. Super easy!! Shipping was a little slow, but the price was nice.

  • Again Many Thanks

    Posted by: Joe Budz


    If I'm in need of filters or new product I will be back in contact with your company.

  • Aprilaire installed

    Posted by: Betty L. Davis


    The package arrived intact. My daughter and I installed the filter. I had installed the last one myself, so knew how to do it. I had called the dealer that installed the furnace and the Aprilaire last summer. They were to come and check the furnace and install a new filter but never showed up. That's why I ordered it directly from you.

    It is unfortunate that the #501 Media product doesn't have built in separators, and release me from the hide and seek process which i have to go through each time i have to change a cleaner...

  • Online filter order

    Posted by: mike5902@aol.com


    We need two 5000 series filter 2X per year--$200/year. The HVAC company did not have them on hand (and they installed the units for us) one time, so I went online. I found the markup by the HVAC service to be $67 each time--every 6 months, so now we are saving $134 a year.

  • Comment on Media

    Posted by: Kathryn Feurich


    As this was the 1st time for me installing the media, I must admit that I found it difficult and more time consuming than envisioned. That having been said, I have had minimal sinus issues since and am thrilled with the effectiveness of this product. Well done, Aprilaire!

  • Now THAT'S is an air filter

    Posted by: cib


    Bought this house about two months ago and finally got around to looking for the air filter and found I had a Aprilaire 5000 on my heating and cooling system. Never heard of them. Did a little research on the web, pulled out what I thought might be the filter...and could not figure it out. But it was obviously way past time for a change of filters. Ordered a new filter, with the promise of instructions on how to install on the filter. Again, pulled the filter, but with instructions inhand...after the 312 steps (just kidding), put it into place and all is well. But, wow, that is an impressive filtering system.

  • Good product, good instructions

    Posted by: frankster14


    Product arrived promptly and in good condition. The instructions were better than most and allowed me to complete the filter replacement in about 20 minutes.

    This air cleaner media came ready to work. The instructions are posted on the back of the box for installation, and look complicated at first. It turns out that it is very easy to figure out and very easy to install. I will be coming back to make sure I have a clean filter every year.

    Posted by: Earl Carlisle


    This is the second filter that I have installed. The first one last year was very hard to install; the instructions are very difficult. I ended up with the filer in an upside down position & I just gave up & left it that way. This year I was determined to do it correctly. After much swearing & anguish I finally figured out the instructions. Next year it will be a breeze an April Breeze.

    I ordered the filter "Media" for my Aprilaire 5000 Whole House air filter unsure if I would be able to change it myself. It arrived almost immediately. I pulled my huge filter box out of it's housing and took everything apart. I threw the old media away and followed the instructions on the box of the new one. It went together pretty easily as the instructions have good illustrations. I was so proud of myself for not having to call for professional service which would have cost me hundreds of dollars. Well Done!

    My Aprilaire whole house air cleaner is a blessing. Not only have my allergies cleared up but I have very little dust in my house compared to others. I have always purchased the filter media from the company I bought the system from. The cost of a replacement filter has been increasing and the last time I bought from them it was $80.00 - then I found your web site and will order from you directly from now on. Thanks again, Jeanette Cunningham

  • Quick shipping but

    Posted by: Mike H


    The filter appeared to be old.. And was very fragile on install; I had to staple a the first pleat back to cardboard part. I looked at the old filter I took out, which was a year in the unit and put some force on the pleats to see if it was me being to rough, but no tear like the "new one" I put in. I've read lots of great reviews so one mediocre one might be a fluke.

    The 501 Media for Aprilaire 500 Air Cleaner was easy to install and met my needs.

  • Media Filter

    Posted by: Carole Geronimo


    I wish that the filter didn't fall apart so easily (where the paper meets the media), I couldn't tape it b/c of fire issues so I snapped it in hoping it would stay in. I wish that the package came with a small tool to clean the wires or you sold something to clean the wires. Also, I replace 2X a year, isn't that right, not just the 1x/year? The filter certainly traps a lot of dust, hair and other stuff;have hot air furnace and it's a must have.

    Our Aprilaire is an integral part of our home's heating/air conditioning. The website allows me to order replacements at 1/3 of the cost that my local HVAC installer charges! Quick shipping means I have it in my hands before I'd ever be able to get the HVAC company to respond to my calls. I'm a senior citizen, retired educator and this is definitely the way to go. Even this old lady can install the filter media alone!
