Merv 13 Filter Material, Air Filters for Stops Dust and Pet Dander as Small as 0.3 Microns (16 Ft²)

I use this material on my vacuum cleaner, to make it into a heap or close to heap Vac. I wrap the factor filter with one wrap and adhere it using rubber bands. It does not interfere with performance on either of my vacs including shark, and works so well the factory filter doesn't need cleaning after use and eliminates vacuum exhausting allergens. Great stuff. Its so inexpensive, I do not reuse it.

Good

Good product!

Filter quality: Top notch Ease of installation: Easy to install

Nice if you are making your own DIY air filter

I decided to try this on my oscillating tower fan in the bedroom. I just opened up the sheet cut it to size and tape it to the back of the fan and it works just fine.

Good but Falls Short on Practical Use I tried this MERV 13 filter material hoping to save money by cutting it to size for various vents around the house. The roll itself is generous—16 square feet—and the material feels sturdy, with enough density that you can tell it should trap fine dust and pet dander effectively. When freshly cut and installed, it does seem to capture a fair amount of debris, so performance-wise it’s doing what it claims. Where this product misses the mark for me is in usability. Cutting it down to fit different vent covers was more tedious than expected, and getting clean edges that sit flush without gaps was tricky. Unlike pre-cut filters with a firm frame, this fabric tends to bow or wrinkle once in place. In one vent it worked fine, but in another it kept slipping out after a few days. I also noticed it restricted airflow more than standard filters, making my HVAC system run louder and harder. That raises concerns about long-term strain on the system. Bottom line: The filtration ability is good, but the lack of rigidity and the hassle of cutting/installing makes this more trouble than it’s worth. If you’re handy and want to customize filters for non-standard vents, this might work. For most people, framed pre-cut filters will be a lot easier and safer for your HVAC system.

I bought this material to filter air in my residence as an alternative to a hepa filter. The popular hack is to use a furnace filter attached to a box fan. This product is cheaper and can be cut to a variety of sizes, which I have done for a small personal evaporative cooler. The filtration rating on these higher rated furnace is not as high as a hepa filter, but it’s still very good.
