Central Air Filters

What brand are you using? I had the #10 home debot Honeywell filters for a few years and they worked pretty well but only for a few days before I noticed the air quality was the same as with the old filter. Recently switched to 3M Filtrete which looks like better quality and I feel like it filters better after a week. It's supposed to be replaced after 90 days like the Honeywell filter. What filter do you recommend?
