Just looking at the features listed, you will see a direct correlation with the devices’ editor’s choice status. For starters, there are attributes essential to allow the device to carry out its air purification mandate. These are the HEPA filter which can remove almost all airborne particles. There is also the UV C light filter whose primary focus is to eliminate germs and viruses, and lastly, the charcoal filter so that odors in your quarters will be a thing of the past.
Additionally, you also have to consider the small form factor of the device, and this allows it to cover 153 sq. ft. As such, you may need to buy two or three to cover a large room adequately. However, this is expensive as you need to spend close to 150 dollars for each unit. Nevertheless, you will still grow to appreciate the investment if you decide to make the purchase.
There are also extra features, such as Bluetooth and WIFI connectivity. If you download the GT app on your phone, you can control the device from anywhere at any time. This means you can pick and choose from the five speeds that the invention provides. Conversely, you can opt for auto mode, which leaves you with less work to do. The device detects the amount of particles in the air and adjusts the speed of the purifier accordingly.

Next up, it incorporates both a HEPA and carbon filter.
Considering that it comes with a remote, the device is easy to use from anywhere in the room. Also, you will notice the three-stage filtration system. Air has to pass through the pre-filter before going through the other two filters mentioned above. As such, you are all but guaranteed it would come out the other end fresh and clean.
Another impressive aspect is the ten-year warranty. Of course, if you consider how much you have to pay for the device, it is wise of the manufacturer to save you money via the warranty should anything untoward happen.

The Germ Guardian AC5350B is quite similar to the Germ Guardian CDAP4500B. You can also tell that both these options are from the same manufacturer. An example of similarities is in the inclusion of different types of filters on a single gadget. These are the HEPA filter, charcoal filter, and the UV C filter. The overall design is also quite similar in shape with a few tweaks here and there.
In the features listed, you are bound to notice the inclusion of a pre-filter. This component serves to trap dust as well as other large particles such as pet hair. Concerning maintenance, you are going to need to replace the filters every six to eight months. You are also limited in the filters you can use if you want the best results from the product.

It uses a HEPA filter with three variable speed settings. You will, however, have to manually set which speed setting you are comfortable with at a particular time of day.
At full blast, the device will be able to purify the air for 160 sq. ft around the device. As such, if you are using it in large rooms, the wise thing to do would be to have two or three of these around.

This is especially handy if you suffer allergic reactions from certain elements in the air. Each device uses an ozone generator to purify the air in the room. It does this by using an air ionizer, which tends to activate oxygen and negative ions. This has the ripple effect of eliminating bacteria in the air and hence removing one of the leading causes of odors.
There is also a dial on the side of the gadget that helps regulate the ozone output. The range you have to work with is between 10-50 mg per hour, and you can adjust this depending on the size of the room, or the air purification needs at a particular time. Also, you are going to appreciate the fact that the device hardly makes a sound while in operation. You can thus leave it on at night in your bedroom while you sleep.

Aside from the features, there are a few other check boxes that you have to tick before you can pick a model to purchase. Some of you may not know what these checkboxes are hence the buying guide below. Consequently, once you have considered everything below, you can be sure the buying decision you make is the right one.
Benefits of plug-in air purifiers
If you have one of these gadgets working close by, maybe not only at home, but when using air purifier for your car, you can be sure that the air you breathe is of better quality. Also, some of them allow you to eliminate nuisance odors. In addition to that, you can get an air purifier that removes pet dander from the air you breathe. This makes it easier to live with that fluffy friend that you love so much.
Features to consider when choosing a plug-in air purifier
Features are still a significant part of the selection process. They determine the capabilities of your device and thus make a valuable benchmark in assessing the suitability of the invention to your home and needs. As such, they are listed and extrapolated below.
Type of filtration
Each particular model will have to have a filtration system to clean the air, and there are various options to choose from.
You may also come across a UV light filtration system. The UV light emitted is powerful enough to eliminate some of the air contaminants in your general vicinity. However, this filtration system has a rather limited range of effect, as is evidenced by the Guardian Technologies GG10002PK. Nevertheless, some manufacturers opt to use this in conjunction with other filtration systems. Our editor’s choice is one such example.
Charcoal filters specialize in being able to eliminate odors quickly, as well.
It beats the point of having such a device if it only functions in one section of the room you use it in. Where you find that the device’s range is limited, you may have to buy a set of two or more. Nonetheless, some devices are quite impressive in the area they cover. The Oransi OV200 is one such device with an area coverage of about 400 sq. ft.
The size of the device is also particularly important as it determines where you place it as well as its portability in situations where you need to travel. The best devices pack impressive features alongside a wide coverage area and all while maintaining a small body.
As is typical with a lot of purchases, you may get a warranty as well. It shields you from having to spend more than the initial investment if the device suffers any complications. However, not all manufacturers will offer you a warranty, and even if they do, the terms may not be favorable. As such, you should read through all warranty documents to see if they work for you. This should also be done in the preliminary stages of the buying process as you are weighing your options.
You will also likely find products with extra features. These include pre-filters and remote controls that allow you to operate the device from across the room. Each additional feature should give you one more reason to purchase a product over other options as you will get more functionality from the device.
You can opt to run the device continuously, or you can choose to turn it on occasionally. It’s all dependent on the air quality in your space and how often you need it cleaned.
This is yet another area that depends on your needs as an individual. You can opt to buy one device with a significantly large coverage area. However, each time you leave a room, you would have to take it with you into the next one. On the other hand, some devices won’t even cover the span of a single room, necessitating that you buy more of them. You can also purchase devices for each room in the house if you so wish.
Whichever way you choose to leave your windows doesn’t matter as the purifier should be able to clean new pollutants coming into the room as well.
Where the top three gadgets are concerned, the Germ Guardian AC5350B makes it into the fray due to its superior filter setup. You have a prefilter in addition to three other filters as well. Most other options have one filter hence the reason this model stands out above the rest and is also considered to be one of the best air purifiers for mold.
Another quality pick making it into the three highest recommended gadgets is the Oransi OV200. If you want a single device for each room, then this is it due to the coverage area. It also features the best warranty in our list. Nevertheless, it comes at a rather high price point, so only order this if you can afford it.
The editor’s choice is an excellent all-round tool to have in your house. It also features multiple filters like the Germ Guardian AC5350B from the same manufacturer. You also get smartphone control via a downloadable app. This makes it easier to operate from a distance. There isn’t much left to do but to log on to Amazon and order your favorite plug-in air filter. Let us know how that goes in the comments section below.
