Breath easy.

So if you haven’t seen already, we’ve got a seriously legit “Our Happi” 1,500 sqft air purifier for sale over at Meh today.

This is a big deal. Because those suckers are expensive.

And even though it seems like shelling out hundreds of dollars for an air filter should be the end of you needing to spend good money in order to breathe good air, it turns out that you also have to replace the filter sometimes.

It’s definitely still worth it—clean air and all—but you’re probably going to be annoyed at the cost of the filters, at least a little bit. (Of course, some of you already have one of these awesome air purifiers and have likewise already been annoyed at what the replacements cost.)

In either case, you’re going to want to find at least a slightly cheaper way to keep yourself stocked with clean filters, and getting one for $50 instead of $65 is definitely a good start.

If you don’t have a fancy air purifier and don’t plan on getting one, you could probably strap one of these to your face and breathe through it directly, but maybe you should just sit this one out. For everyone else, get one. Maybe two. You’ll be stoked the first time you need one and you’ve already got it on the shelf.
