- CarVac 6y agoMERV 13 is hospital grade, apparently, but HEPA is far better (and more restrictive) than even a MERV 16.
- lambda_obrien 6y agoThanks, I forgot that was the case, I looked it up and you're right. I use merv 14 in my home and it eliminates smoke from forest fires, but not allergens, I'm going to get a hepa filter next time.
- CarVac 6y agoPollen or animal allergens should be totally captured by a MERV 14 filter. Smoke is much more challenging to filter out, and that's where a HEPA would be better (but not necessary unless you're filtering incoming air directly).
