Replacement Filter Compatible with Dr.J Professional AP401 AP402 & GCZ AP402 Air Purifiers, 4-Stage Filtration CADR 400+ m³/h Air Purifier for Dust Odor Smoke (1 Pack, White)

A very economical way to ensure you're home is fresh and clean. I have breathing issues as such I'm not a fan of home fragrances, this keeps the air clean and fragrance free at all times. The last unit lasted close to a year. When you have multiple it spreads out this work. Circulation of the air is whisper quiet. The only time it automatically speeds up is when someone opens the doors. Other than that you literally forget it's working.

The machine is so simple to use.. You basically just unpack, insert the filter, plug it in and it automatically goes to work. This product is very quiet and has cut back on my dusting.. The air even looks crisper.. I only wish that it released a nice room scent freshener...The only downfall is that it continues to shut off and doesn't help much with the odors of smoke...🤨 Needs some Improvement.....

I like this air purifier. It's very quiet - I finally had to change out the filter and it was very easy to install new one...another reason to like it.

these are awesome air filters my room smells so refreshing. these are my second buy they are remarkable filters

Keeps the air in house smelling fresh and clean wirhout alot of cover up spray or plug in scents.

This is not a name brand but one made by another company. The filter looks like it is working but the image of a filter shows on the screen on the machine It never did that with the filters made by the same company.

Sometimes I just don't understand how to navigate Your site and sometimes don't get my orders correct.I make a mistake such as getting two pairs of boots exactly the same when I only wanted one. Then operating your site to return is very difficult too.I'm a senior with very limited computer and cell phone skills.But I did find out.I can return them to the store and that's good.However your customer service at the nominee walmart she was not very friendly. I like being able to order things from Walmart and have them delivered.It helps a lot but sometimes I wish that you could deliver everything.I've ordered at one time but I understand many times things come from different places. I have contacted customer service at walmart in menominee and the lady I talked to was kind of rude. Her name My, there was a lot of background noise so hard to understand.

The description was misleading. Make sure you check your filters measurements before purchasing. This was a few inches too short for my DRJ. I should have known by the price that it was just too good. Bummed
