Well, hey everyone. I'm getting ready to change the filters on our Lycon Air filter that we have here in our home, and it looks like it's very, very straightforward. You just push here and here, that pops up, and then you take the lid off, and then what you do is you're able to remove the filter. And I'm really interested to see what this looks like. Yikes, look at this. All right, so this is what the— you put 2 of them in, but this is comparing the old to the new, and it's interesting to think that that Could have ended up in our lungs. So we'll just slide this new filter right in like this, and do the same thing on the opposite side. Pull this filter out, and then put the new one in. Then put the top back on, and looks like we are ready to go. We hit go, and back in the game. So, like an air, this is a HEPA 14 filter. We use them in our home, and you know. We really care about the quality of the water we drink, we should be paying attention to the air that we breathe.
