Review on 🌬️ Filtrete 20x20x1 Allergen Defense Furnace Filter by Andrew Agarwal

The difference in house dust is quite noticeable with this class of air filter. Do you want to breathe in that dust or pay a little more for a quality air filter? Just be aware that at least on first use as it catches dust, which your cheap filters don't, it starts to get a little concave and noisy. That happened to me when I put in the first filter after about 45 days. It's my second day so I'll see, but even if you do it once a month the health benefits are worth it.
