Air purifiers can help relieve asthma, coughing, and other respiratory symptoms caused by allergens such as dust, pollen, and mold.

Aside from your feelings, how can you tell if it's not a gimmick?

Seeing is believing 😊

Air purifiers with air quality sensors can monitor real-time air quality, allowing you to not only monitor your air purifier's efficiency but also the air quality in your home 24/7.

In this post, you will find the best smart sensor air purifier that shows air quality, how it works, and the hottest questions.

Part 1. What Is an Air Purifier with Air Quality Monitors

Air purifiers with air quality monitors can detect air quality in your home in real-time.

The built-in air monitors use two types of sensors: PM sensors and gas sensors.

PM (particle matter) sensors are commonly found on home air cleaners, detecting the number of air particles and displaying the results via its LED color on the control panel. PM sensors are adequate for home use because your home's air contains few chemicals.

Air cleaners with gas sensors are typically found in industrial air purifiers and are used to detect chemicals in the air such as ozone and nitrogen oxide.

Part 2. How Does a Smart Sensor Air Purifier Work

The air purifier's built-in PM sensors can detect the number of harmful particles in the air.

There are two types of PM sensors: infrared sensors and laser sensors. Both work in different ways.

Infrared sensors: As dust passes over an infrared light-emitting diode, it will reflect light. Based on the reflected light intensity, the sensor generates a PWM signal that indicates dust concentration directly.

Laser sensors: When fine particles in the air enter the area where the laser beam is located, the laser light is scattered, and the photoelectric effect of the photoelectric detector generates a current signal. The concentration of fine particles can be obtained after amplification and processing by the circuit.

Air purifiers with air quality monitors show the air quality in different ways. The Purivortex V3 air cleaner, for example, displays the air quality via the control panel's LED color.

Part 3. The Top-Rated Pick Air Purifier with Sensors

To help you cut through the marketing hype, I've rounded up the best air purifier with an air quality sensor in 2022.

#1. Purivortex V3 - The Best Air Purifier with Sensors

V3 is a large room air purifier that can cover spaces up to 1,076 ft². This air filter is the best choice if you are looking for a smart sensor air purifier for your living room, apartment, office, or large bedroom.

It features a 4-in-1 strong filtration system that can remove up to 99.99% of air pollutants, such as pet dander, dust, mold, hair, smoke, and pollen, and absorb all smells, like cat & dog smells, VOCs, etc.

This air purifier with HEPA filter comes with two washable fabric pre-filters in turquoise green and basalt grey, allowing you to customize the air cleaner to match your décor.

As previously stated, this quiet air purifier has sensitive dust sensors. The V3's built-in dust sensors can detect the number of particles in the air and reports the current air quality via the LED color.

When your home has high levels of air particles, the color will be red. Your home has the purest air if the color is green. You don’t have to worry if the color is yellow because the air is still safe to breathe ☺️

If you are unsure about the effectiveness of an air purifier and want to stay informed about air quality, the V3 is unquestionably the best option.

Note: If your air filter is operating 24/7, the color should remain green unless the air quality suddenly deteriorates, such as during a wildfire near your home.

Another excellent feature of this product is auto mode. When you set the air purifier to auto mode, it will adjust the fan speeds based on the current air quality in your room.

Part 4. Air Purifier with Air Quality Sensor: FAQs

Here are the most common questions about air purifiers with air quality sensors, along with the right answers to make sure you know everything before you buy it.

1. Do Air Purifiers Improve Air Quality?

Yes, air purifiers, particularly HEPA air filters, can capture 99.99% of air pollutants. Thus, air purifiers improve air quality.

2. How Does an Air Purifier Measure Air Quality?

Air purifiers with air quality indicators have one or more built-in sensors to detect the amount of dust and other particles in the air.

These air purifiers, such as the V3, typically use LED color to display the current air quality in your home. Green, for example, usually indicates that the air quality in your home is excellent.

3. My Air Purifier Says I Have Poor Air Quality. What Should I Do?

Firstly, you should identify sources of air pollution in your home, for example, your friends are smoking in your home.

If the problem is indoor air pollution, open your windows to ventilate the house and place your air purifier near the source of air pollutants.

If the air pollutants are from outside, such as wildfire smoke, you should close the windows and run your air purifier at full power.

4. Do Air Purifiers with Air Quality Monitors Detect Dust?

Absolutely yes!

An air purifier that has a built-in air quality monitor uses a dust sensor to detect particulate matter.
