Measured my kitchen ceiling and it required a grease filter so thin it was not available anywhere in any store locally, no one had a clue how to assist me with my needs. I found range hood filters online checked out the web site thought I had found gold. I measured exactly what I needed and thickness even had charcoal layer built in, mind you mine is extremely thin. Purchased one it arrived in perfect condition, quickly too. It was custom made. I immediately installed and it’s perfect fit. Best experience ever for an online store. They keep you informed from order accepted to update on status to shipping and tracking order a real gem to do business with 100% satisfied customer. Ralph Washington state
