    We called a tech to service our air conditioner. He was going to charge $130 for a new filter.We said no thanks and found the same filter for 1/4 the cost at Aprilair. Thank you Aprilair.

    The fit was a little tight (pinched) but fit okay for the frame.

  • good product, but hard to use

    arrived on time and in good condition, but was hard to install (as expected). The printed instructions were terrible, but I was able to install it thanks to a YouTube video.

    I ordered this part some time ago and I did not install it until 9/21/12. I was waiting for the cooler weather; I was concerned about the installation because of th possibility of one of the parts beaking down. That did not happen. I received help from your company, which was great. Bill Cunningham Bill579@juno.com

    Posted by: Brian


    Recently ordered a long overdue replacement 2400 filter and installation was very easy. Although the price of the filter was fair, I did not like the shipping options and additional charge. I was in no hurry to get my repplacement and would have preferred the option to choose a cheaper shipping method that took longer to arrive.

  • Satisfaction..Good job

    Posted by: Pat Gallagher


    I appreciate the email to warn me that it is time to change mu filter. Once ordered online, the product arrived quickly. I intend to keep this process going as it makes it very easy to be a customer.

    I ordered an air filter replacement to have on hand in preparation for the oncoming summer. The website was easy to navigate and I received the filter replacement in a timely manner. I will shop on this site again.

    I have just bought a new home and found out that it had an Aprilaire home air cleaner system. Bought a new filter and the air quality in the home is cleaner than a regular filter. Since I have asthma and sever allergies I haven'thad any issues. I am very satisfied.

    My experience with purchasing the needed filter online from Aprilaire was very satisfactory and much less a problem than trying to find a local provider and acquiring the filter from them. Thank you very much for your assistance. Jilma Steck

    Order came right away. Easy to order. Would order this way again.

  • My first replacement

    Posted by: Pat


    This was the first time I replaced the filter myself. I must admit that it was easier than I expected and know that after doing it a couple of times, it will not take me much time at all. I was also told by my service contractor that you could not get this filter except through them so I was very glad to find that to be not true.

  • Easy to use

    Posted by: OhioMom


    I am very pleased with the product. The filters are easy to install and work wonderfully.

  • shipping costs too much

    Posted by: Dennis


    $11 plus for shipping was much more than I expected. Would appreciate cheaper option than FedEx.
