1. Blue Pure 211+ Air Purifier 3 Stage with 2 Washable Pre-Filters

Blue Pure 211+ makes a good choice because it is easy to use. To get it to work, simply plug it to a power outlet and then press the single button at the front to turn it on and run it at three fan speeds. If you want it to stop running, simply press the same button to turn it off.

Blue Pure 211+ provides unquestionably excellent cleaning performance, leaving your room in its best condition while constantly getting rid of toxic air. This unit operates with 30 to 60 watts of power, making it a good option for the power-conscious user who’d rather not add an extra cent to their annual power bill.

This air purifier doesn’t feature a True HEPA filter, but its filtration system is still powerful enough to get the job done. The pre-filter is responsible for large particles like dirt and hair. The particle filter helps to get rid of particles as tiny as 0.1 microns, including pet dander, mold spores, and pollen. It also features a carbon filter which helps to get rid of toxins like chemicals, smoke, and cooking odor.

Blue Pure 211+ has wider room coverage, going up to 540 square feet the very moment you turn it on. Its ACH rating is quite commendable. At 5X in just an hour, you expect this to have an air-changing rate every 14 minutes.

Even as LEVOIT continues to improve the performance, value, and cost of its air purifiers, LV-PUR131 remains one of the brand’s best models. Several tests show that this model’s performance is impeccable because it cleans air thoroughly and it doesn’t make noise during operation.

For the record, the biggest issue with this model is the replacement filter, it’s quite expensive. And for some people, this might actually be a deal-breaker.

LEVOIT LV-PUR131 has a 3-in-1 filtration system that helps with cleaning the air. The pre-filter deals with large objects, most mold, fungi, dust, pet dander, and pet hair. The activated carbon fiber helps to remove smoke and bad smell, and the True HEPA filter helps to get rid of particles as small as 0.3 microns.

This air purifier also features 2 unique modes: auto and sleep modes. The auto mode eliminates the need to set the fan speed manually. Instead, it detects and diagnoses the quality of air in the room and then decides which fan speed is appropriate to use. On sleep mode, this unit operates at the lowest noise level possible, so you can use it at night without worrying about the quality of your sleep.

You will love this air purifier because it is ozone free. What this means is that it doesn’t use ion, which is usually responsible for traces of ozone.

Many affordable air purifiers have one thing in common; they don’t have smart features built-in. it is the same case with LEVOIT Vista 200, a unit under $100 built for people under a very tight budget. But just because it doesn’t have a smart sensor doesn’t mean it doesn’t work well.

The filtration system of this unit is quite impressive for the price. Generally, LEVOIT Vista 200 has a 3-in-1 filtration system that comes with all the necessary filters to get the air purification job done.

One of the best things about this air purifier as far as design is concerned is its size. it is quite compact, and it is best recommended for people who don’t have a lot of space.

Although Renpho Air Purifier is a relatively new product in the market, it is getting into the limelight quite fast. In fact, it’s one of the few entry-level air purifiers that score good ratings for durability and low noise level. It would be best if this unit has a remote control, but it functions just fine without it.

If you’re someone who’s looking for an air purifier to get rid of molds from a small room, then this is for you. That’s because it can cover only up to 100 square feet, beyond which you won’t get the best results.

Buyers Guide

Air purifiers aren’t equal, they come from different brands, their overall sizes vary, and each model has its unique features. So, here are a few things to look at before buying one for your home.

Check the ACH Rating of the Purifier

An ACH rating tells you how many times an air purifier cleans your home every 60 minutes. Obviously, the higher the rating the better the machine. So, if you can get a unit with a 5x or 6x ACH rating, go for it. A 4x is a standard rating, but anything below that can only work effectively in small rooms.

Determine the Size of Your Room in Square Feet

Air purifiers have different room coverage, so it’s important to measure your house in square feet to know its size, then you can use this measurement to pick a purifier while keeping the ACH rating in mind. For example, if the measurement of your room is around 200 square feet, it would be best if you choose an air purifier with an exact room coverage or more.

Noise Level

You already know by now that many purifiers have two speeds. A few options come with five speeds. Each has its noise level, it’s best to choose an option that makes less noise, particularly at night.

Determine the Maintenance Cost

Next, determine how much it would cost you to maintain an air purifier. It’s best to evaluate the maintenance requirements for several units to determine what your budget can handle. Once you have the right budget stats, pick an ideal purifier with the above factors in mind.
