InvisiClean Sensa Air Purifier – H13 True HEPA Smart Air Quality Sensor for Bedrooms, Allergies and Pets, Large Rooms, Smoke, Dust, Allergens, Odors, Carbon, Ultra Quiet, No Ozone IC-5120

Purchased mainly because I already owned the InvisiClean Aura which uses the same filter set. The Aura has been running virtually non-stop for 2 or 3 years now without issues and I'm hoping for the same out of this one. So far ran it through several tests and everything seems to work. The lights are a little bright but that's what the sleep mode is for, and yes, all the lights go completely off! Simply press the sleep button again and they all come back on. It is VERY quiet, quieter than the Aura. I also purchased a 2 pack of Pureburg filters for under $30 so I'm covered for my next filter change. I'm a happy repeat customer! As a word of caution, the inside switch by the filter can be a little finicky. You need to be careful replacing the filters or if you drop/shake/move the unit to hard. Just remove the filter and re-seat it properly and the unit should come right back up running.

Upon receipt, the filter fan appeared to be broken. I could get all the electrical features working, but right out of the box the fan would not engage. I would have given this a one star if it weren’t for the manufacturer support, I received. It’s an American company based on the west coast. They provide a slip of paper with their website and phone number listed in the package so you don't have to look up anything for support. When the unit didn’t work, I called the number. They were most apologetic and offered to ship me a new unit immediately. This support earned them a second star in my review. Rather than going through an exchange with Amazon, I decided to take them up on their offer. The new unit arrived in 4 days.The new machine arrived as promised by the manufacturer. They included a UPS shipping label to send back the old one at no charge. I set it up and it is working well. I am leaving it on "turbo" mode for a while to get things in my house started.They have an indicator for air quality. Even with dust and pet dander in the air, it indicated the air quality was good. I thought perhaps it was broken, until I decided to cook a couple of pork chops in a cast iron skillet. This released some smoke and a lot of order. The air quality indicator immidiately turned red, indicating poor air quality. I put the fan on "turbo", and within an hour the air quality indicater returned to blue (good), and my cooking orders were gone.Their design is dirt simple. The filter is easy to remove and replace. The front cover comes off to access the filter, and it is held in place with magnets, making it pretty much fool proof. It draws air in from the sides of the unit and blows it out the top. I feel comfortable leaving it back against the wall and out of the way. It has an “Off” switch which some of the larger machines do not have. It uses a 2-filter system, first, activated charcoal and second HEPA filter. You can periodically clean the charcoal filter with a vacuum (using a brush) to give longer life to the both filters.

Had a competing product from Levoit. Regarding air purification, this model is equal if not better than the Levoit. Definitely quieter and I like the self adjusting speed based on air quality. Where this unit excels is not air purification, but electricity usage and EMF emissions. I realize the opinions on EMF (magnetic and electrical radiation) vary from I don't care to I wear a lead lined hat 24/7 so for what it's worth to folks as I am not here to debate the merits of EMF exposure - this unit produces drastically less EMF than other purifiers, especially magnetic. The Levoit would hit 50-75 Milligauss once you were within 3 feet of it and the EMF would not drop to safe levels until outside of 8 ft. This unit's EMF at close range is shown in the attached pic (exposure under 2 Milligauss for extended periods of time considered "safe"). Now if you have an air purifier tucked in a corner away from bodies on a consistent basis then not a problem IMO. But if you have an air purifier in your bedroom, especially within 6 ft of you, you are getting the benefit of clean air while negating it by having the equivalent of a small microwave running right next to you for 8 hrs. Whats the point. If you can have clean air and also no other emissions then its a win-win while being priced competitively and doing a good job cleaning the air. One note regarding Amazon . . . . be wary I got my 1st unit and it was clearly used so back it goes (missing instructions, packing inside missing, filter was out of bag and installed!). Got the second one and clearly new (filter in sealed bag, unit in a plastic bag, instructions, etc).

I was looking around for a good air purifier that is within budget and does a great job for its size. This is by far one of the best items you can buy for such a reasonable price. Looking at air purifiers that easily are 3X to 4X the price was where I started, so ending up with this one surprises even myself. Once I came to the conclusion that they are all using the same filter, or type of filter, I started looking for one that was at a price point that I would be comfortable in purchasing, if I wanted to purchase more than one. I just received it today; 03Apr20, and I have already seen a difference in the air quality in my house. The smell and strangely, the feel of the air is noticeable. I wish I had purchased two of these at the beginning. No worries, the next one is already ordered.The Pros:Multiple fan speeds to get the job donePrice per unit is amazingLow setting is whisper quietWeight of the unit is remarkable lightReplacement filters are super inexpensiveCons:None at this time. I may update this review later depending on longevity of unit.Great buy, you will be glad you purchased this.

Using this in our dart parlor (16x16) where my husband and others smoke. It completely keeps the odor under control! I’m so pleased with its performance. The more smoke, the louder it gets but we’re not trying to sleep so it’s ok. I recommend!
