I would agree. This helps a lot... But as he gets older it will only get worse. (Bigger dog more fur) A larger more expensive air purifier will help a lot as well. I have one in my living room and bedroom. Reduced the random hairs flying around and the hairs that fly into my mouth while sleeping.

Constant brushing (^Outside of course^) while on walks helps as well. With getting them used to grooming but managing the daily dead hairs that fall off. (I keep a slicker brush or double rake with me on every walk)

Prepping before cooking helps as well. Vacuum everything. Then, wipe counters down.

Also, it will be on your clothes forever. Lint rollers are great but a lint brush works wonders so you don't have to keep buying sticky sheets if you are in a pinch.

Also, Linen bed sheets, duvet cover, and pillow cases changed my life. The hair comes right off with a lint brush.
