No one can help you as you have fundamental misunderstanding of the industry.

1. Purifiers are sold on square footage of the room(s) used. You didn't list it so 0 people can recommend one.
2. 0 purifiers with a washable/cleanable filter are purifiers. The only standard for purifiers is their ability to filter the air. You can quantify this via the rating, with the 99.9% gold standard being a HEPA or PM2.5 unit which has a filter that needs replaced.

Now if just want a "purifier" that doesn't do anything other than make noise, move air and filter cigarette butt sized objects, you can get you a box fan and tie a washable filter to the back, but make no bones: This ain't a purifier.
