5 out of 5 stars
Great filter
Overall I really like the filter. The frame is made out of plastic, lightweight, easy to assemble. The only drawback I have with it is that the sides tend to pull in towards the center of the filter when the AC is running. I can't see if this creates a gap for air to flow unfiltered but even if so, that 'should' be minimal. I'd suggest a slight redesign with a 'tee' in the middle of the sides to put support in the middle of the filter. Love this filter so much that I bought a second one. This way I can place the used filter in the washing machine and rotate the second filter. Before purchasing the second filter, I'd keep a second 'standby' filter for use when doing laundry. Aside from that, it seems to be wonderful so far.

    The filters showed up at the perfect time. I honestly didn't expect them to work and be a lifesaver. I have used mine for about a month. You can see the difference in color from the amount of dust. I was able to simply vacuum the filter and place it back in. Recommended to wash every 3 months so I haven't gotten that far yet. Assembly was a snap and filter fit tight around frame.

    I've had regular disposable and washable by hose a/c filters. These are so much easier to use, saving me time and money over the years. I just pull them out, unzip and place the fabric in the wash, then the dryer. Back on the frame they go. They dry super fast. What a great investment.

    Got sick of constantly replacing my furnace filters, this has exceeded my expectations and then some. Traps quite a bit of dirt/hair so I was it every 2 months instead of 3. It’s held up in the wash and gentle drying. Recommended to wash on gentle/delicate cycle.

    This is so clever! The hard plastic frame fits together the way tent poles assemble. The filter itself is like a stretchy pillowcase that skips over the frame and zips closed. It was incredibly simple to assemble and install. I haven’t washed it yet, but it looks like it will be very easy to do. It even comes with a magnet and marker so you can remind yourself when to wash it. I’m excited to not be throwing out furnace filters every month or two.
