Review on 🌬️ Holmes C Humidifier Filter - Ultimate Air Quality Enhancement by Mark Allen

On Holmes' website they are half the price. Luckily someone else pointed this out earlier. So in terms of value, I don't see how anyone can give this a 5 star rating. We sell 2 of these each winter and they used to sell 2 packs (for $20). So keep that in mind when ordering. One probably won't be enough. We use ours every night from around November to March. It would be nice if they lasted a little longer. Oh, I should mention that we have a whole house water filtration/softening system. I would have thought this would stop hard water from building up quickly, but they spoil quickly. In desperation they can be cleaned/rinsed and put back in, but they kind of start falling apart when you take them out.
