Permanent Air Filters

Liz bought an air filter. It is supposed to be one of those "permanent" Hepa filters. But that's a big scam. We bought a Honeywell 50150. We bought it mainly because we don't want to be bothered buying new air filters every few months. Because we are both allergic to our cat, and dander is a big issue, we wanted to get a good air filter we could run pretty consistently.

However, this permanent air filter thing is a big scam. You see, while the "air filter" itself is permanent, they have a "pre filter" which is not. So you have to go and buy a new "pre filter" every six months or so.

So while technically they did not lie to me, I feel a little bit mislead.
