This one is a great device for those who are in a tight budget. You’ll get a glimpse of all the great features in such an affordable price. The only downside is, with a CADR of 83, it’ll take time for this device to cover 500 sq., ft. Yet, we’d say a little waiting is acceptable because of the great filtration it provides.

Check Price on Amazon

Bottom Line
This product comes at a very cheap price, basically even half of the cheap models out there. So I’d say the filtration and air flow you get is decent. Also, it’s safe because it doesn’t emit ozone. As for the night light, it can’t be shut down, so it’s something you have to live with. But if you accept this little downside, you’ll get greater value for the money compared to other products.

10. PARTU Air Purifier | Best Room Air Purifier For Mold

Partu is yet another portable air purifier model. It comes with a stylish but compact sleek black design and slope-like top. But don’t get fooled seeing the physique. With a powerful motor, high CADR ratings, and three-layered filtration, this one doesn’t fall far behind the top models.

Bottom Line
One of the major problems with cheap models we discussed earlier was the night light that can’t be shut off. This one has a lighting setup consists of 7 lights and it can be shut off. The memory function is also a convenient feature. It works well within the space of 160 sq. ft. But I’d say the price is already low for such great features. And it’s still better promising to deliver big and failing.

Frequently Asked Questions about Large Room Air Purifier

Albeit small amount, ozone can still cause you coughing, chest pain, throat irritation, lung inflammation. It might cause asthma patients to experience more asthma attacks.

However, renowned manufacturers paid heed to this matter and came up with purifiers where you can opt to use or not use the Ionizer.

Other air filtration methods come with safety measures. They use systems such as Activated Carbon Filters and HEPA filters that absorb harmful particles. Thus, they are safe to use.

3. Do Whole House Air Purifiers Dry Out the Air?

Answer: That’s one of the common misconceptions. Usually, air purifier filters don’t remove humidity from the air. However, there is an easy way to know if your purifier dries out the air. See if the device has any dehumidifier settings, a water tank or hose. If none of them are present, it’s not drying out the air. Because there is no place for the collected water to store and drain.

If you’re concerned about dry air on your home, you can use a humidifier. They have several benefits similar to air purifiers.

Answer: The EPA (Environmental Protection Agency) suggests that you monitor your health right after transferring to somewhere new.

If you experience health problems right after moving to a new place, or after remodeling, re-furnishing it, this can be the symptom of air problem.

If you have breathing problems or asthma, and your problem suddenly intensifies, this can be a sign of air quality problem.

5. Do Hepa Air Purifiers Eliminate Odors?

Answer: The main task of best air purifiers is to remove toxic particles out of the home. Often, they are the cause of bad smell within the house. Thus, you can say air purifiers can eliminate odor in a way.

However, do they actively remove odors? Most of them don’t. However, some come with odor removal features. They contain specialized carbon or charged filters to catch and eliminate odor. Anyway, our recommendation would be not to purchase air purifier just for odor removal purpose.

Final Words

Air purifiers come in different size and capacities. You can install it for a confined space, or a whole house. There are some models that are compact and can be carried easily. Some models look like voice-activated personal assistant devices and they blend nicely with the surrounding.
