Air purifiers are great for filtering indoor air. To recirculate the air, they have fans and filters. However, when using an air purifier for effective air filtering, you must be cautious.

An air purifier, at its most basic level, is an indoor device that collects and filters dangerous particles before releasing new, healthier air. It shows that most air purifiers remove indoor pollutants including bacteria, dust, pollen, odor, and pet dander, to mention a few.

An air purifier can help humans avoid respiratory ailments and allergies by limiting the transmission of hazardous particles and allergens. This device is commonly seen in businesses, homes, learning institutions, and hospitals.

Who needs Air Purifiers the most?

With Existing Health Concerns


All of us, especially those with allergies and respiratory disorders like asthma, require clean indoor air. Better air quality reduces allergy and asthma triggers at your office, home, school, and car.

Live in a Modern Building or Home

Buildings in the modern time are more energy efficient. As a result, the structures are better sealed to meet the regulations. When this happens, it disrupts the airflow circulation and traps pollutants inside the home. In terms of artificial ventilation, for example, you are more likely to require an air filter.

Near Pollution Sources

Vehicle exhaust, construction chemicals, fresh paints, and other pollutants are all present in certain structures. If you live in those buildings, you can use an air purifier to remove all of these dangerous particles from your indoor air.

A perfect air purifier filters both particle and gaseous contaminants from the air without creating ozone or other potentially dangerous byproducts. The air purifiers made by Levoit are the safest on the market. They don’t utilize any electrical filtration in their air purifiers and only employ mechanical filters.

About Levoit LV-H133 Air Purifier

For those seeking a good air purifier for large spaces, the Levoit LV-H133 air purifier is a great option. Levoit is regarded for delivering some of the greatest products. They are, nonetheless, quite near to achieving success with this product.

The filtration components inside the purifier are primarily responsible for the excellent performance. To begin with, the pre-filter captures bigger particles and serves as a sort of screen for the purifier’s main HEPA filter. 

You’ll definitely enjoy the benefits of this purifier if your home is filled with pollutants and odors. The activated carbon filter follows the HEPA filter and actively removes odors and aromas.

Effective 3-in-1 Filter


This purifier utilizes a three-stage filtration system. It includes a pre-filter, a True HEPA filter, and an activated carbon filter in a 3-in-1 cartridge. The preliminary net filter eliminates large particles such as hair, lint, pet dander, and dust.

The H13-grade true HEPA filter follows the pre-filter. The True HEPA filter does the majority of the filtration. In this manner, it removes majority of contaminants and odors.

This filter captures and eliminates particles as small as 0.3 microns from the air, with a 99.97 percent efficiency rating. Pollen, fine dust, cigarette residue, and a variety of other contaminants fall into this category.

An activated carbon filter is the final stage. The filter made of granular activated carbon absorbs cooking odors, household aromas, cigarette smoke, and VOCs.

Each of the three filters is packaged together which is simple to replace. The filter has a 6 to 8-month life expectancy. Check the filter replacement indicator to see how long your filter has left.

Touch-based Controls


The air purifier uses touch controls to operate. Every mode and button are easy to use. That’s not everything. It is appealing because of its attractive UI. Simply push the button once to modify a setting or perform a function.

Indicator for Filter Replacement

Let’s take a look at the filter indication first. This button flashes when the filter needs replacement. This should happen after 6-8 months from the previous time you replaced your filter. To reset the filter after replacing it, push the button for three seconds.

Timer Button

The timer button is located after the filter indicator. In any mode, you can set the timer for up to 12 hours. Set the timer if you don’t want the purifier to run all the time.

Sleep Mode

Another important feature is the sleep mode. Running an air purifier 24 hours a day, even while sleeping, is suggested. Select sleep mode to ensure that the fan does not disturb your sleep. The purifier will run at the lowest fan speed possible, allowing you to have a good night’s sleep.

Air Quality Indicator

Finally, there’s a gauge for air quality. The color of this indicator changes based on the air quality in the area. When it becomes blue, the air quality is good; when it turns red, the air quality is bad. To clean the air, set the purifier to the highest fan speed setting.

Sleek Design + Highly Efficient

The purifier has a CADR of 274 cfm thanks to its robust filtration technology and fan. As a result, it’s ideal for medium and big spaces. It can purify the air in rooms up to 410 square feet and can clear the air in such settings in 12 minutes (5 air changes per hour).

It can clean large rooms up to 1,030 square feet in 30 minutes and uses 47 watts while doing so. When compared to most standard light bulbs, this is less. As a result, the purifier saves energy. You don’t have to worry about power usage if you use it all day and night.
