Even with filters, it annoys me from an environmental perspective that the default flow leads you into having them ship you the exact number of filters your house needs, every two months.
Do filters have a shelf life? If not, or if it's sufficiently long, I'd rather they just send me six filters once a year, instead of one every two months, or something like that. I get that some people might not have enough storage space to pre-order like that, but it's otherwise completely unnecessary to send one at a time.
(The only plus I can think of to the one-at-a-time model is that getting a new one in the mail is a nice reminder to replace the filter. But I also have this thing called a "calendar" that I can use.)
You can totally do the six filters once a year, that's how I usually do it, but the smoke is destroying filters pretty quickly. If you want minimal brain power, getting them every 3-months (or what your normal cycle is) is fairly optimal, since getting new filter === time to change the filter.
I keep extra filters in the garage for about 6 months before they rotate into use. I'm not sure if they have a shelf life or not but we've never noticed any difference and neither have our indoor air sensors.
