1. LEVOIT LV-H126 Air Purifier for Home with True HEPA Filter

The Best Overall

LEVOIT is a popular and large brand with many high-quality products. The LEVOIT LV-H132 with the offer of True HEPA Filter is one of their best models at a budget price.

At first glance, many customers admit that this air purifier has an elegant and simple design. To be more specific, the front surface is a blue piece of cloth, giving it a soft and comfortable look.

Besides, with a height of 10.5 inches and a width of 7.9 inches, it is compact and lightweight. Thus, users can put it anywhere they want, even on the shelf or the table.

Along with that, the air purifier filtration system consists of 3 stages. This means that the air will go through 3 steps before being released back into the house.

  • Pre-filter: First of all, the unit takes the air from the back. The intake air will come through pre-filter to get rid of any big particle that can be clogged in the filters. This helps to prolong the lifespan of the other two filters in particular and the air purifier in general.
  • Activated carbon filter: In the second stage, all the bad odors like cigarette smoke, pet odors, and kitchen smells will be eliminated.
  • True HEPA filter: The final stage includes removing all the remained pollutants. This stage can clear out up to 99.97% of all microcosmic particles of around 0.3 microns. This means that even the smallest pollutants will be eliminated and your house will be clean and fresh.

What is more, the manufacturer does pay attention to power consumption. The brand has installed three fan speeds, which are low, medium, and high. Hence, you can control it by turning the knob on the front face to adjust to your preference.

Most interestingly, it also features a filter reminder wheel. It has the numbers of from 1 to 12 with an arrow. Each number stands for each month in a year, for example, number 1 for January or number 9 for September. What you need to do is set the arrow pointing at the month when you need to change the filter.

However, this air purifier only comes in one color choice, which may be confused for those who want another color from white. Still, the blue and white color on this look elegant, doesn’t it?

Although the name states 3 in 1, in fact, it is a 4-stage air purifier. To be more specific, there is a bonus filter added by the manufacturer that can be either turned on or off, depending on the intended use of users.

  • Pre-filter: Like other air purifiers, the pre-filter in this one has a duty of cleaning large particles like pet fur, lint, and hair around your house. This stage makes other filters work with less pressure and thus, can last longer. However, it should be washed every 3-4 weeks to keep it in good condition.
  • True HEPA filter: This stage can make you free of worries about particles of as small as 0.3 microns. This is a great advantage of a HEPA filter, which can remove up to 99.97% of contaminants, giving users good health.
  • Activated carbon filter: At the third step, unpleasant odors, smoke, and smells will be filtered and simultaneously, it absorbs harmful gases like benzene or formaldehyde.
  • UV-C light: It is an optional stage, which means you can turn it off or on without affecting other filters. What you need to do is to touch the button on the top of the air purifier, and it will deal with bacteria, viruses, and fungi effectively.

Moreover, when it comes to quietness, this air purifier is almost quiet. Its noise level is only about 30 – 50 dB, depending on different fan speeds. Still, even with the highest setting, the noise is just as much as a refrigerator, even quieter. Thus, it becomes a useful tool when used in bedrooms as it does not interfere with your sleeping.

One additional feature that is favored by many users is the timer. It will save energy, even when you forget to turn it off as you can set the time when it shuts off. Besides, it is comparatively economical. It costs only under $100 to own and about $20 for replacement. It also uses a low amount of electricity in their lifespan.

One another air purifier we would like to introduce to you today is the RENPHO Air Purifier RP-AP068. With a height of 11.4 inches, a width of 11 inches and a weight of only 6.5 lbs, it is considered the most compact air purifier on the list.

And now, let’s talk about the most important part of an air purifier. With this RENPHO product, there are 3 stages in the air filtration:

  • The first stage is known as pre-filter. In this stage, such large airborne particles as pet fur and hair are captured, ensuring a longer lifespan for the true HEPA filter. The pre-filter is washable and needs cleaning twice or four times a month.
  • In the second stage, the true HEPA filter will trap large pollutants like dust, smoke, pollen, or pet dander as well as small particles.
  • The last step is the activated carbon filter, which includes the tackling of different types of odors like cooking smells, cigarettes, and even outdoor smells.

Along with that, in terms of design, although it is not revolutionary, it still looks pleasant. Combined with that, the materials are taken from California, which means they have to satisfy all the strict Californian requirements. In short, compared to its counterparts, it is comparatively more superior.

What is more, it is absolutely easy to operate. Specifically, what you need to do is to press the intuitive buttons and it will turn on. Also, there are not too many buttons on the control panel. Just simply pressing on one button multiple times to change into other settings.

Some users may worry about the noise some air purifiers produce when putting it in bedrooms. However, this RENPHO is completely different. It has a sleep mode with the quietest setting of only 37 dB. This mode does dim all unessential lights, leaving the room in the dark. Hence, users will get into sleep much faster.

The most useful feature is attributed to the filter replacement indicator. The light of this system will flash whenever it is time to replace a new filter. Usually, the filter should be replaced every 6 months to keep the air purifier working properly.

The only drawback is that it functions properly only in a limited coverage area, of around under 103 square feet.
