The Ultimate Air Purifier Buying Guide: Everything You Need to Know


MAY 21, 2024

Clean air is a precious commodity in today's world. With increasing pollution and allergens, investing in an air purifier has become essential for maintaining a healthy indoor environment. 

Breathing clean air is crucial for our lungs, heart, blood circulation, and overall health. The air inside our homes can be more polluted than we realize. Using an air purifier can help remove pollutants and harmful particles from the air. With so many options out there, choosing the right air purifier can be confusing. This ultimate buying guide will walk you through things you need to know when purchasing an air purifier.

Understanding air purifiers

An air purifier is a device that cleans the air by removing pollutants, allergens, and contaminants. It works by pulling in the air and passing it through various filtration systems.

These systems help improve indoor air quality by capturing particles like dust, pollen, pet dander, and mold spores, leaving you with cleaner air to breathe and providing numerous health benefits.

However, it might surprise you to learn that not all air purifiers are created equally. Just because the word includes ‘pure’ doesn’t guarantee that it will improve the quality of your air. In fact, some of the most popular air purifiers only do little to nothing to improve your air quality.

With this air purifier buying guide, you can have a good understanding of what you should look out for when shopping for the best and most effective air purifier for your home.

Top 5 important factors when choosing air purifier

Filtration system and technology

The heart of an air purifier lies in its filtration system and technology. It's important to note that some air purifiers combine multiple filtration technologies to provide effective air cleaning. When choosing air purifiers, consider the type of filtration system and technology used and ensure they align with your air quality needs.

Filter replacement

Dust, pollen, etc. that gets collected on the filter over time can reduce airflow and the air purifier's cleaning efficiency. A clogged filter can cause excess wear on the machine, reducing its lifespan. How often to change the air filter depends on how long the air purifier runs each day as well as how polluted a room or living space is. Some air purifiers come with filter replacement indicators as well as filter subscription service, so you don't have to remember when to change the filters.

Power, efficiency, and noise

When choosing an air purifier, pick a powerful yet energy-efficient model to have effective air purification while saving money on electricity bills. Also, consider the noise level of the air purifier, especially if you plan to use it in bedrooms or quiet areas. Look for models with noise ratings below 50 decibels for you to have a peaceful environment and uninterrupted sleep or work while improving your air quality.

Design & portability

It is recommended that you choose an air purifier with a design that can complement your living space. Air purifiers with a modern and minimalistic aesthetic can suit the majority of household settings. Also, consider choosing air purifiers that are small and lightweight with powerful air purification, so you can easily carry them around for more thorough purification throughout your home.

Brand reputation and speciality

Not all brands are created equally. When it comes to choosing an air purifier, consider picking a brand that is trusted and highly recommended by media outlets, celebrities, and many families. Furthermore, choose brands that are designed by air quality experts specializing in latest air purification technologies through countless research since their products are guaranteed to be high quality and innovative.
