2 small sans & one large sans I wrote one review, they deleted it. I bought a small Sans for my bedroom because I have multiple medical issues. I then bought another one for an elderly man that I am caregiver to, THEN I bought a big unit for the kitchen and living room area. You advertised that the units would eliminate the dust issue in the house. It did not. The dust seems to be worse like it is just floating it around. Fraudulent advertising should be punishable with a huge fine! I've had all three now for at least 3 months. Your review tips says you want feedback and when I put my honest review, you deleted it, which is what I am sure you will do with this one.

Poor customer service I have been on hold for customer service for 28 minutes and then hung up. On the talk icon on the website I have waited for 30 minutes after entering my question and then disconnected.

I signed up for their auto filter… I signed up for their auto filter replacement program because I live near a landfill having a chemical reaction, so this was very important and not a one-and-done. They notified me last month it was time but then nothing showed up. Come to find out they were on back-order. I had to research it. They NEVER notified me and my machine turned to a red signal notifying me it was time. Finally, they came in and it was shipped. I live in the same state and even the same area of the state of this business (southern CA) and now I am looking at day 6 and the filter is still NOT here. I have contacted them a few times now to find out they will NEVER let you speak to a human. All communication must be done online. No phone service. Now I discovered that they have handed off the delivery to UPS which notes they can't deliver because they need a code for a gate. I have NO gates and neither does my neighborhood. So, I contacted Sans and they told me to contact UPS. I am NOT UPS's customer I am Sans customer. I still don't have the filter and I have now cancelled the program with Sans which was not easy either. The program only has a skip delivery option, not a cancel. You have to contact their online customer service yet again. I have no proof they actually canceled it. Do yourself a favor and pick a different company. My time is more valuable than this bull. Zero for customer service. The product is okay but not quiet at all if you need to run it on high which we do need to do.

Buyer Beware This is not True Sans, would you like to see a copy of the transcript conversation? I still have it. I replied back within minutes with the recording, which showed the problem in both machines. John didn't address the first issue at all. Of the second SANS unit issue, he only said not to worry as the warning light would probably come on in a few days to a week. When I pointed out I had changed the filters once before and reset both lights at the same time. So they both should have come on together or at least a week apart, that's when SANS stopped talking. Oh SANS don't you wanna talk anymore 😂 _____________ I purchased three units and they work decently. Not as great as they claim but it definitely helped with my allergies to an extent. Then I started experiencing minor problems with two of my units. When I brought the problem to the companies attention, the company line was, "This has never happened before." When I pointed out there is always a first they stopped talking. Decent product Really bad customer service. The reason you don't hear the negative is bc they block all bad press.

I really love this product...example..I… I really love this product...example..I was telling my sister how well it automatically cleans the air, when my son came home from work , took his work boots off and set them beside the Sans...long story short..the machine went bezerk...blue light turned red and fan turned up on high..when the laughter from all subsided he decided he should clean his boots before coming in the house..lesson learned..well done Sans....well done :)
