Pre filter bowing doesn't lay flat

"I love the product buy this white prefilter is bowed on the original and it seems the additional ones are as well. It is like its just a scooch too big ??"

Helped our allergies!!

"Great filter! We had the original for a year or more and was able to easily clean it, but with this terrible allergy season I figured a new one of these would help, and it did!"

Great filters

"If you're the owner of an Alen air purifier, it's important to keep it running at peak performance with regular filter changes. The Alen Air Purifier Replacement Prefilter is an essential component of your purifier that helps to extend the life of your HEPA filter by trapping larger particles, such as dust and hair, before they reach the HEPA filter. This prefilter is made with high-quality materials and is designed to fit perfectly into your Alen air purifier. It's easy to install and replace, with no tools required. Simply slide the old prefilter out of the purifier and slide the new one in. One of the best things about the Alen Air Purifier Replacement Prefilter is that it's washable and reusable. This means that you don't have to replace it as frequently as your HEPA filter, which can save you money in the long run. When it does become dirty, simply wash it with soap and water and let it air dry before reinstalling it into your purifier. Another benefit of the Alen Air Purifier Replacement Prefilter is that it helps to improve the overall efficiency of your air purifier. By capturing larger particles, it allows your HEPA filter to focus on trapping smaller, more harmful particles like bacteria and viruses. Overall, I highly recommend the Alen Air Purifier Replacement Prefilter to anyone who owns an Alen air purifier. It's an essential component that will help to keep your air purifier running at its best and improve the quality of the air in your home."
