The Flanders Natural Aire filter, Fits up to 20 X 30, cut-to-fit

I am so glad I found this product. We were really struggling with the washable filters in the air handling unit in in Manufactured Home. Not a good choice but the only one we had that fit the unit. We tried trimming disposable filters. Not a good idea. This is the perfect solution. Sturdy. Washable. Breathable. Easy to cut for a perfect fit. Thank you!

the filter looks OK, though the color is dark green, I asked the seller what made it dark green, so far no answer.

We have a furnace upstairs at work with odd-ball sized filters so we use this stuff and it works great, just wash it out once a month and put it back in and replace it when it starts falling apart.

I've been using natural air filters for over six years and I've been satisfied with the performance and the ability to clean and reuse them. At the beginning, the price was only $13, then went to $16 and now, the price has grown astronomically. I thought the more technology progresses, the lower the prices should be, but.........I was surprised, though, when I received yesterday my Amazon orders, among them, the filter and find out how perfect and securely prepared was for shipping. I wish that kind of packaging be used for fragile products that have arrived, sometimes, almost broken. I wash the filter every month, but during the pick usage, such as winter and summer months, I wash it every two weeks, for energy saving and better performance of the unit. I'll order another one, for I like to have one cleaning and the other behind the grill.

This item is exactly as advertised and seems to be a high quality product. Very easy to cut to size and replace your old filters. Delivery was very prompt and they provided excellent communication throughout the process.

Too stiff to handle Be careful--I wore gloves when cutting it, as recommended. But I accidentally got some powdery pieces on my hands later and it felt like invisible shards of glass on your hands that won't wash off.

I had a filter like this for several years and this is the exact replacement. This filter provides good filtration and is flexible enough to bend and retain it's shape. It can be cut with heavy tin snips or a utility knife. You can easily wash it out with a hose but you may need a degreaser if it is extremely clogged.

It works okay. I have an odd size filter, so I have to cut to fit. If I did not have to do this, I would purchase higher quality, regular filters.

works great!
