HEPA air purifiers: This type of air cleaners adopts HEPA filters, such as H11, H12, H13 filters. Portable air purifiers with true HEPA filter are able to block all airborne particles, like dust, pollen, smoker, both large and ultrafine particles (larger than 0.3 micrometers in diameter).

This type of portable air purifiers removes 99.9% to 99.99% of particles, offering true clean air. But, the HEPA filter cannot absorb smell or odors. It is used for blocking particles.

However, please note that those HEPA-like or HEPA-type air purifiers do not meet the standards of true HEPA purification. Hence, DO go for portable air purifiers with TRUE HEPA filters.

Activated-carbon air purifiers: These air purifiers use the activated-carbon filters to kill the unpleasant smell, odors, and gases.

Typically, many air purifiers use both HEPA filters and activated-carbon filters to remove particles and absorb odor-causing molecules in the air, which is helpful to turn dirty air into true clean air.

Electronic portable air purifiers: This category of air cleaners use electrostatic precipitator and ionizers to charge particles in the air, so that these particles stick to plates on the devices by a magnetic-like attraction. However, this type of air purifiers will produce ozone. Hence, this type of air cleaners is not recommended.

There are several important points that you should keep in mind when you are about to purchase a portable air purifier.

Filter types: Select those air purifiers with true HEPA filters or activated-carbon filters, since these air purifiers will produce clean air without dust or particles.

CADR: Clean air delivery rate (CADR) measures how much an air purifier can filter, indicating the volume of filtered air an air cleaner delivers. Please choose the portable air purifier with the suitable CADR based on your room size.

Room size: Though higher CADR typically means better, it is not the golden rule that always select an air cleaner with huge CADR. For example, if your room is 10 m3, you don't need an air purifier with 100 m3 CADR, since it may increase your maintenance costs.

Hence, get one with the right CADR based on your room size.

Noise level: It may so annoying if the air purifier makes a loud sound, especially when you put it in your bedroom or home office.

The noise level varies based on the fan speed. Higher fan speed partners with louder noise. For your sweet dream, it is advised to choose a portable air purifier with less than 30 dB.

#4. What Makes a Good Portable Air Cleaner

What is the best portable air purifier?

What's a good desk/small true HEPA air purifier?

A good portable air purifier should come with the below MUST-HAVE features.

Compact size or easy-to-move design: A portable air purifier should be small and compact for ultra portability. Or, some bigger air purifiers should come with pragmatic handles or wheels for effortless moving.

True HEPA filter: The core of an air purifier is the HEPA filter. Only true HEPA filter can block ultrafine dust or particles, and provide you with true clean air.

Switchable fan speed: It is necessary for an air cleaner to have the tunable fan speed, so that you are able to adjust the fan speed based on your specific needs.

Different fan speeds produce different noise levels. Hence, adjustable fan speed offers flexible noise level adjustment, so you can control the level all by yourself.

Low noise level: The noise level produced by an air cleaner matters especially when you place it in your bedroom.

During your sleep, it is undoubtedly troublesome if the air purification system rings loud. Hence, a low-noise air purifier (less than 24 dB) during your sleep.

Switchable night light: The night light, especially the warm yellow color, like the Purivortex 201B Pro, makes your home cozy and comfortable.

The warm yellow night light, with 500-750 nm spectrum, stimulates the secretion of melatonin (a hormone primarily released by7 the pineal gland at night), putting you to good sleep.

Plug-in design: Air purifiers are engineered to run continuously for your 24/7 clean air need. Hence, an air cleaner is better when being plugged into an outlet for continuous power supply.

Those so-called rechargeable battery-powered air purifiers in the car, or for the stroller, and those necklace air purifiers, is not that efficient to convert the dirty air into clean air due to the limited power.

So, for the best air cleaning effectiveness, a plug-in air purifier would be the ONE you should go.

Timer: If you don't want to turn the air purifier 24/7, you can schedule how long your air purifier should keep turning on. That’s the reason why an air cleaner should come with a timer for more flexible

Ozone-free design: An air purifier should be clean, not just producing clean air, but also "clean" to the Earth.

Those old-fashion portable ozone generator air purifier (with UVC LED), will do harm to the Earth's ozone sphere, which leads to the greenhouse effect.

Hence, a good air purifier should be ozone-free, environmental and eco-friendly.

#6. What Portable Air Purifiers Can't Do

Currently, air purifiers can only remove the airborne particles – those floating particles. Dust, mites, pollens that have settled down on the ground cannot be caught by air purifiers in time. Hence, it is better to turn the air purifier on 24/7 in order to filtering out the dust and particles in time – before they stick to the ground.

#7. How to Make the Most out of Air Purifiers

You can maximize the effectiveness and performance of the air purifiers with below helpful and useful tips.

Put it in a "sealed" room (not completely dead sealed 😂): Close the door and the windows. Turn on the air purifier. A rather sealed space prevents most dust and particles from entering the room, so the air purifier can simply clean this specific room's air, able to maximize the air cleaning efficiency.

Place it wisely: Place the air cleaner in a room where you stay most frequently (if you just get one unit). If you have multiple air purifiers, place one for each room. Read this article for how many air purifiers you need for your home.

Besides, place the air purifier on your table or on the ground, and make sure there is no any other stuff blocking the air inlet or outlet. Otherwise, it may impact the efficiency of the air purifier. Leave enough room between the air purifier and the wall.

Adjust the speed: Turn the fan speed to the maximum level when you are in the room, and turn it to the minimum level when you are in the room to avoid the noise.

Change and clean the HEPA filter regularly: HEPA filter determines the filtration efficiency. For the best performance, it is advised to change the filter every 3-6 months.

Also, use a dry hairbrush or small vacuum to clean dust of the filter for good ventilation. If the HEPA filter is an activated-carbon type, dry the filter in the sun once per month.

Pay attention to the environment: Don't place the air purifier in a humid (such as bathroom) or high-temperature environment. It will impact the air purifier's effectiveness.

#8. Other Ways to Help Improve Air Quality

Besides air purifiers, there are other handy ways you can try to improve the indoor air quality.

Get an exhaust fan in your kitchen: An exhaust fan helps improve the ventilation inside your kitchen. Also get several exhaust fans for your laundry room and bathroom.

Try NOT to use chemicals: Minimize using the chemical-heavy cleaning products and don't keep paint, glues, insecticide in your daily living areas.
