Review on 🌬️ High Performance Nordic Pure 20X25X1M12 6 Pleated Furnace Filter by Tone Hatton

The Nordic Pure Merv 13 air filters are impressive and capture a lot of dust and other contaminants like pollen, but these Merv 12 Nordic Pure Air air filters don't capture dust, which leads me to believe they don't Also don't catch pollen. We decided to try these Merv 12 filters because they were a lot cheaper and thought they would perform the same as the Merv 13, but we couldn't be wrong. Today I replaced our filter and this filter was almost never dirty; it was just light brown. With Merv13, the filter would be dark gray and full of dust, but not this filter. We switched to these filters 6 weeks ago and my 11 year old son has had severe itchy eyes and ears for a month and my asthma has worsened. I suspected it was the filters but didn't believe it as the Nordic Pure Merv 13 filters were so great and so much better than the 3M filters we've been buying for years. But when we saw that the filters weren't catching anything we went to Revain to find a Revain warehouse deal on some Nordic Pure Merv 13s which we luckily found. So if anyone in your family has asthma and/or allergies I would not recommend this filter. Update: We have replaced this filter. filtered with Nodic Pure Merv 13 and after 3 days everyone felt better. No more allergies and asthma attacks.
