Meh. Smaller than others.

While I get that some measurements are different in construction, this is considerably smaller (half an inch on one measurement) than the Honeywell filter I was replacing, meaning the filtering capability is also smaller. I'm bummed, to say the least.

Healthy home on a schedule

Finding the filter size I need is hard locally, but with filter buy I can get high quality filters sent directly to me when I need them so I am less likely to forget to change them. That all is great but the prices are also fantastic, much cheaper than comparable filters in typical hardware stores.
