Buying Guide for Best Plug-in Air Purifier

If you are looking to purchase a reliable plug-in air purifier, our detailed buying guide will be pretty helpful for you. Remember, before jumping to any conclusion, you should check all these below-mentioned guidelines briefly. We have also made a comprehensive list of premium features that you should look for while buying an air purifier.

Filtration Method

The filtration method is one of the most critical buying factors that decide any air purifier’s efficiency. Here are some of the most common types of filtration methods commonly used in air purifiers.

HEPA Filters: The HEPA Filtration is a highly recommended option while buying an air purifier. It’s one of the most effective filtration methods that can easily trap 99.97% of the airborne pollutants such as dust, mold, pet dander, virus, bacteria, and many others.

Activated Carbon Filters: Even though activated carbon filters are mainly used to remove foul odors, they are quite effective against many airborne pollutants.

UV Light Filtration System: The UV light filtration system is very strong and powerful when removing air contaminants. However, this type of filtration system offers a limited range as compared to other filtration methods.

Ionizer Filter: An ionizer filtration system is also becoming popular nowadays. This type of air purifier filter produces negative ions and traps the airborne particles in the air.

Washable Pre-Filters

Before buying an air purifier, you should also look for washable filters. These filters will not only save a lot of money but will also help you to extend the lifespan of the primary filter.

Filter Indicator Light

The indicator light is a very useful feature that can tell the user about the filter replacement. Even if you forgot to replace the filter on time, this indicator light blinks automatically to remind you about filter replacement without damaging the air purifier.

Air Quality Sensors

Air Quality Sensors are also one of the most important features for checking air quality. It will help you determine how polluted the air is in your room so that you can adjust the cleaning speed accordingly.

Room Size

It’s very crucial to purchase a plug-in filter system according to the room size. A reliable air purifier should be capable of handling the entire room; you should check for those particular air purifiers that can easily handle the air quality of your entire room.

Certifications

If you want to judge the quality of any air purifier, you should look for some specific certifications first. There are many certifications available such as Energy Star, AHAM, CADR, and many others. With all these certifications, you can easily pick up the best product without doing any comprehensive research.

Warranty

Last but not least, a money-back warranty is one of the most important buying factors that you should never ignore before making any decision. You should always go for those particular brands or manufacturers that are confident about their quality. If the air purifier you have selected doesn’t offer any money back or replacement warranty, they are not optimistic about their product quality. As per our experience, 1 Year full money-back guarantee is enough to trust any brand.
