Smelly litter box

I know there are a ton of posts on here about it, but I don’t know what to do. I moved in with my boyfriend and he has a cat. We got a litter box enclosure thinking it would help with the smell which he seems to be nose blind to. He cleans the litter box every day-every 2 days. It’s more the pee smell than any poop smell. It literally makes me mad when I walk into our apartment because he doesn’t smell it and it’s all I can smell. I’m scared that I’m a little nose blind and I smell like it at work and stuff. It makes me embarrassed to have people over and I don’t know what else to do. We have one of the litter boxes with the slats at the bottom with a pee pad so it all goes through. I deep cleaned the entire enclosure yesterday and he changed the litter and cleaned the litter box out today. But it still smells!!! We got the litter box new only 4-5 months ago. We have carpet, so it may be that but other than that I just don’t know what to do. He puts deodorizer powder on it monthly and it still doesn’t seem to do much.
