ONA block

So I saw a little product called ONA (odor neutralizing agent) for about 8 bucks and decided what the hell my cat box reeks..... anyway it is a little canister that you screw the lid of it off and put it in the room or by your ac intake and it makes the house smell really nice. I deff give it a thumbs up at the moment I just have to see how long it will last before I can smell the odors in my house again.

where did you get it?

I have seen a home made air purifier that used this tuff, but have never been able to find it.

ordered it from be well hydroponics, got a nice orchid too

yeah the blocks work for a few weeks then i flip the puck upside down as they will dry out and loose the smell
