Review on Nordic Pure 16X20X2M12 3 Pleated Condition by Jeff Sorensen

We have been using them for over 2 years. Then the packaging of the last box ordered was different. plain text. There are no flowers or a pure Scandinavian name on it. One of the filters in this box kept whistling like it was the wrong size and air was going through it. 2 out of 3 were ok. A few months later another 3-pack. The same problem, only this time 2 out of 3 whistle loudly when the device is running. Unacceptable. It looks like the manufacturer has changed or the quality standards have changed along with the packaging. Will NOT buy again after many years of using Nordic Pure. I just ordered another brand. Buyer warning! If you don't like a loud whistle filter, don't do it!
