The filters are well built and easy to wash. I keep 2 on hand. I have one in use and I wash the other one clean to keep on standby for next month. Rotate and repeat!

I will definitely recommend ElectroDust filters to family and friends!
The filter was professionally packaged and well manufactured. The product seems solid and should hold up well.

Thanks, have a nice day.
This exactly what I was looking for to replace the one I was using for the past 10 yrs. I'm quite happy that I could buy them directly from the manufacturer.

By the way they were delivered on time as advertise.

Thanks for a very good product.

ElectroDust filters provide higher than industry average air quality and are built to higher standards. Our filters are environmentally friendly, allowing you to wash and re-use them over a 10 year lifespan.

After just 10 months of using our filters, you will begin to realize savings. Furthermore, because ElectroDust filters are more efficient at capturing dust and foreign particles, you won’t require duct cleaning as often, saving you even more money. Less dusting means a healthier home.

It depends on your furnace. Check the dimensions of your opening for the filter. Most furnaces use a 1-inch.
