What pet should i get?

I live in Southern California and I really want a pet. I have a regular parakeet and a sun conure. I live in a condominium. I’m allergic to dogs and cats. Is it possible to get a good HEPA air purifier? I’ve had a rabbit but I had to give him away because of his pee smell. I DO change his litter box everyday. I have carpet flooring. My sun conure makes a lot of noise but the neighbors never said anything. I have a really small backyard. What pet is best for me?
Lastly, my mom doesn’t like reptiles. Esp snakes and frogs and slimy animals. Sorry if I didn’t add that.
