These filters hold up MUCH better than the cheaper ones you can buy from retail stores. The filters appear to filter, but allow for ample air flow.

Have not used them yet so just based on the look & type of materials used they do look like they will perform well. Once used I will update rating.

You get what you pay for if you buy in bulk.

Could be made better. The only way to save money through this website is to buy at least four or more. The pleats are uneven compared to the best (3M). It was worth a try.

The filters are a good product. Change them every 2 months. Couldn't find 2023 size in stores. Glad your company has them.
