I’m looking to buy an electric air purifier for my home. I’ve heard that they can help with allergies, dust, and even pet dander, but I’m not sure which one to choose. I want something that’s effective, quiet, and doesn’t take up too much space. Also, should I go with a HEPA filter or another type of filtration? Any suggestions on models that work well in medium-sized rooms? Thanks! 
We’ve been using a HEPA-based air purifier for about a year now and it really helps with allergies. The model we chose is quiet, and it covers a medium-sized room easily. I highly recommend checking the square footage coverage before buying.
A HEPA filter is usually the best for allergens and dust. If you’re looking for something to deal with pet dander, I’d suggest an air purifier that also includes a carbon filter to handle odors.
I use a Dyson air purifier that’s both a fan and air purifier in one. It’s a little pricey, but it works great in a medium-sized room, and it has a HEPA filter. It’s also fairly quiet and has a sleek design.
