Customer Ratings & Reviews

Performs exactly like it says! We have pets and a smoker and allergies in the house and it definitely does its job. We've been sleeping so much better since we got it!

When it comes to air purifiers, there seem to be two design camps. The first is minimalist -- a simple box in which one button controls everything. Then there are the designers like the ones behind Shark Air Purifer 3 in 1, which has more functions, display options and controls than you can count Let's see. It is an automatic HEPA air purifier of course. It also doubles as a stationary or oscilating fan, with up and down vent controls, like you probably have in your car. And it can operate as temperature controlled space heater . Automatic or manual operation is possible, giving users the choice of letting the Shark 3 in 1 control the fan speed based on temperature (in heat mode) or air quality (the rest of the time). Air purification is going on no matter what option you choose and Shark claims big round filter inside captures more "harmful micro pollutants" than its competitors. It's nice to have all these options but it does make this thing much more challenging to operate than any other other air purifier I have used. This is not just a fan in a box, which is essentially what many brands are. This fact becomes abundently clear as soon as you pull it out of the box. The 3 in 1 is literally covered with stickers that explain how all the different controls work....and reminding you to pull the filter out the clear plastic shipping bag before you run this thing for the first time. Each sticker has a QR code too, which takes you to online videos to explain the not so simple operation of this thing. I advise you watch them, and leave all those stickers on for the time being because there is a lot take in. That's all the more important since 3 in 1 comes with no printed instructions at all and unlike most other electronic devices of this era, does not have an app to walk you through everything. Once you understand how the unit works, it's not really too bad. But there are a lot of controls and buttons to consider and some things don't work at all (like the heater) if you don't have every dial in the correct position. It's a bit daunting at first blush. A round hocky-puck style panel on the top of the 3 in 1 provides overall control of the unit. It is magnetically mounted and can be easily removed ri to carry around if you want remote control, a nice touch. The various buttons on the remote give you control over fan speed, oscilation, target temperature (in heat mode), timer, display dimming and what information you want to see in the display. There is also a toggle on the side of main unit that switches the air flow from front to back. The thinking here is if you just want air purification and don't want a fan blowing on you, the air can exit unobtrusively out the back the unit. This control must be set to the front vent to run the heat. There is a 1500 watt heater inside that cranks out a good amount of heat, which can be controlled by setting a target temperature or simply running full blast all the time. Regardless of whether you are using this or fan mode (front air flow) , you can opt to manually control fan speed or select Auto and let the unit to decide how fast to run based on environmental conditions at that moment. A lighted circle display on the front chnges color to indicate whether the air quality is good, medium or bad. The fan is very quiet most of the time but will get loud if higher fan speeds are necessary to deal with poor air quality. There are bewildering number of display optons related to air quality, so you can see if the pollutants in your home are more of the small virus variety or larger pollen type crud. Four types of pollutants are measured and each one gets a number detailing its quantity in the air at that moment. There is also an overall "clean air" number, which should be at 100 if your air is nice and clean. A button on the remote allows you to switch between these various displays. But actually seeing that display is a bit of a challenge. While the big color ring around the display is nice and bright, the numbers and text in the center are so dim and/or so small, it is hard to read them unless you are inches away. Not a great design. Sleepers who cannot tolerate any light at all will be happy to know the display can be dimmed or turned off entirely. The buttons on the remote control can also be difficult to read in low light since it is not back lit . And since it is round, it is sometimes hard to determine whether you are holding it upside down. If you could see the display, it would tell you other things including time remaining on your timer, current temp or target temp in heat mode and time left before you should replace the big round filter inside. Shark says it should be replaced every 6-12 months. Filters cost about $60 at the time of this review, so clean air does not come cheap. But Shark contends you will get very clean air from the 3 in 1. The big round filter is supposed to remove pet dander, dust, smoke, pollutants and allegens in a 500 square foot area. Expect a bit of a chemical smell on startup. It goes away in time. As far as aethetics go, the Shark Air Purifier 3 in 1 is a bit more attractive than the plain boxy designs of most competitors. Shark opted for a compact round unit (white or black) with a grid at the bottom where air comes in and a faux metal ring (actually plastic) around the top. The same material surrounds the display on the front of the unit, giving it a more hi-tech appearance. Overall, the Shark 3 in 1 seems to do a good job of cleaning the air, as well as providing plenty of versatility with fan and space heater modes. If you can figure out the daunting controls and handle the heft price tag, it's a good choice. .

Purchased to replace heater and air purifier so we could just use one device. Works as expected.

This unit has done a great job as a purifier and a heater. I have used it ever day since I got it (about a month and a half) and the filter is till at 90%. The only downside is it’s a bit bigger than I thought it would be and is somewhat difficult to move room to room.

I would give 6 stars! This is a terrific Air purifier. Has a nice solid weight and build. The round wireless remote sits nicely in the top and stays put magnetically. It will operate all settings with line of site. (Has to see the purifier unit to work) You can also customize the display with the remote. 3 functions allow for purified fan only, Enhanced purified air and Purified heat. Yes, you heard correctly. This unit puts out a good amount of heat. There is approximately a 25 second delay when switching from air to heat due to heating element warming up before dispersing the warm air. You can change air direction to come out front or back of unit depending on the type of air you want. There is an adjustable vent in front to direct air flow up or down. The front display shows present air quality, room temperature and preferred/set temperature along with other customizable readings. The panel light has 3 settings-Bright-50%-No Light. Select auto to have the purifier decide on what settings are needed to purify air. I found the lowest fan setting is Wisper quiet. The fan overall has a very solid smooth sound so even on higher speeds does not bother me at all. 3 different PM readouts indicates types of impurities that it is filtering. This purifier is feature rich and flexible which also includes oscillation mode to help circulate the air.

This has a lot of nice features built in, but it is rather large. I'm sure the size of the unit is driven by the size of the HEPA filter, which fills up most of the lower portion of the unit. The colors are somewhat muted, but it's not going to disappear into a corner of your room. The display is informative and useful, and you can choose what you want to see. It is nice to be able to glance over and see the air quality and temperature. You can set it to run automatically, ramping up as needed to deal with variable air quality. You can also set the heater to maintain a desired room temperature. You're not going to get a large amount of air flow if you're trying to use this a fan to blow air around the room. The air discharges out of a fairly small, louvered port in the front. There is a small lever you can use to adjust those louvers up or down. You can also set it to oscillate automatically to distribute air more evenly around the room. The remote is cool, but maybe not the most ergonomic. It is round, and designed to sit in the center of the top of the unit. If you're operating it locally, you still use the remote, you just don't take it off the unit. It's an interesting setup, but if you lose the remote, you're out of luck, because there's no other way to operate the controls locally. I love the overall operation, just wish it could be a bit smaller.

I overall have liked my machine so far. Just wish you can set a temperature when the fan is going like you do with the heater.

This product is amazing!! It works great. Easy to use and I can already tell the air is so much better. Definitely 5 stars!!!

I’ve been looking for one of these with winter approaching so that I can climate control my newborn daughters room whilst also keeping the air clean for her. This is the perfect solution and I’ll sleep easy knowing this is keeping her safe at night. I was really surprised at the lack of online functionality. It seems everything these days is “smart” and I’m a little worried I won’t be able to remotely check that it’s functioning properly. There is a non-ergonomic remote in the shape of a hockey puck that can be difficult to operate properly if you have smaller hands. The remote also enables a child lock on the controls by holding two buttons at once. You can also turn the display off for night time use. It purifies the air constantly no matter if you have it on fan/heat mode or auto purify mode. It claims to “maximize the purification” on purify mode, but I left it on for a couple days and the “clean air percentage” never rose above 90% from 80%. Turning the fan on full blast was much more effective in only a couple hours so if you need to scrub the air quickly I recommend this method, though it is loud. Overall it functions adequately. It does the job, but the clunky remote, lack of smart features, and manual mode switching has room for improvement.

This is great heater. Just takes awhile to warm up to the mid 70's from start of 61. But it does keep me warm when I need it.

This is best air humidifier. More function and good price

I love the product. But the replacement filter is $87. Just a FYI.

Why is the CADR in the specifications 0 cubic ft per minute?

Good product but the price was much cheaper on Amazon
