When you suffer from seasonal allergies, an air purifier can help you breathe comfortably at home. An air purifier reduces pollution in indoor air by filtering airborne pollutants, therefore improving the quality of life for the people living there.
A good air purifier removes virus particles, eliminates pet odors, and improves the quality of indoor air. Furthermore, they are able to minimize wildfire smoke and air pollution indoors. It is certainly appealing even to those without allergies to have an air purifier.
There are so many air purification machines available that tout different methods of purification, that deciding which one will work best for you and your family can be challenging.
The first thing you should determine is how much you can afford to spend on an air purifier. Is it better to have an ionic air purifier or a full home filtration system? What about an activated carbon air purifier? Let us help you sort through the best air purifier options and answer those questions.
We selected these best air purifier options based on careful testing and consideration. All of these air purifiers can improve the quality of your indoor air, remove smoke and airborne pollutants, and offer fresh air.

1. Honeywell HPA300 HEPA Air Purifier
The Honeywell air purifier is a bit more expensive than other HEPA models, but it is able to cover a larger area than most of the other purifiers we compared: 465 square feet. This Honeywell Home is one of the quieter models out there, despite its bulky design (it weighs 21 pounds).
It gives you good control over setting timers and checking whether the prefilter or filter needs replacement. When it comes to great performance and a reasonable price, the Honeywell HPA300 is hard to beat.
2. Blueair Blue Pure 211+
Among air purifiers for large spaces of up to 650 square feet, the Blueair Blue Pure 211+ is our top choice, especially when there is an open floor plan or high ceilings. It can filter up to 50 cubic feet of air each hour. It reaches and maintains low particulate levels faster in such challenging environments.
Compared to the Mighty, the Blue Pure 211+ has a much higher up-front cost and operating costs (about $1,150 over five years), but they are comparable to the costs of most other large-space air purifiers we’ve examined. We found it to be exceptionally fast and quiet, as well as attractive.
3. Coway Airmega 400 Smart Air Purifier
An air purification area of 1,560 square feet makes the Airmega 400 ideal for extra-large rooms. The machine is large, but it is needed to house the power fans and filters so it can effectively work to clean large rooms.
When the machine was used for the first time, it went into overdrive on automatic mode, detecting unsafe levels of pollution in the air. A full clean sweep of our two-floor home was no problem for the machine – our test subject lives in a multi-level home.
As the name implies, night mode is good for, well, night use; it’s quieter, but also functions as a low-power mode when the air quality is good, so your air quality remains good. Those looking for app connectivity will need to consider the Airmega 400S, as the Airmega 400 does not have it.
4. LEVOIT Core 300 Air Purifier
It is a good choice for people looking for a budget-friendly air purifier. Aside from having good CADR ratings (145 for pollen, 140 for dust, and 141 for smoke), it also offers a decent performance range (215 square feet) and is appreciated for its quiet mode. With Levoit’s QuietKEAP Technology, you can sleep comfortably and enjoy clean, purified air.
Although a budget air purifier, the Core 300 uses three stages of filtration, which can be found on higher-end units as well. This camera does not have an auto mode, but the timer feature makes up for it, and the features and price of the Core 300 are unbeatable.
5. Mila Smart Air Purifier
The CADR rating of Mila’s rooms is up to 447 in spaces up to 1,000 square feet. Unlike most air purification systems, Mila’s powerful unit has an in-depth display that shows information most air purifiers only show with an app (and Mila’s app, in itself, provides a wealth of information).
When you set Mila to auto mode, the app will tell you the time it will take to reach the target air quality index (AQI) and how its result compares to the outdoor air quality as reported by your closest air quality monitoring station.
As well as monitoring temperature, humidity, and CO detectors, Mila provides a wealth of useful information and insight.
Air filters used in the air purifier are specifically designed to address the needs of its users. The app contains filters, for instance, for pet owners, new parents, and overall clean freaks.
There is one downside to the Mila: it has a manual on/off switch, which means that you can’t power it on or off remotely, which seems odd since the device is so intelligent overall.
How to Choose Best Air Purifier?
To choose the right air purifier, you’ll need to determine where you’re going to use it. Plug-in air purifiers can’t clean the air inside a whole house; instead, you should isolate specific areas, such as a bedroom, kitchen, or living room.
You can select an air purifier that can effectively circulate and clean the air of a room based on its size. Small spaces, such as a nursery or bathroom, require a tabletop model. In addition to being able to handle larger areas, a floor model can still be moved from room to room easily.
The replacement of filters should also be considered. It is possible to end up spending hundreds of dollars annually on filters if certain models require regular replacements.
When purchasing a model, make sure you consider what type of replacement filters you’ll need and how much they cost, as well as whether you can afford to replace them regularly. In the alternative, you may reduce the effectiveness of the air purifier by failing to replace the filters as recommended.
Sound is also a factor that can be influential. It’s more comfortable to use an air purifier at all hours if it has a low-decibel sleep mode and variable fan speeds.
The term HEPA refers to high-efficiency particulate air filters. There is no finer type of filtration, capable of capturing particles smaller than 0.3 microns. Nearly 99.97% of airborne particles include bacteria, mold spores, pollen, and dust.
Consider the Clean Air Delivery Rate, or CADR, of an air purifier when choosing the best one for your room or area. A typical purifier will list the square footage by which the entire volume of the room is circulated per hour.
What is the frequency of changing a filter?
Regular filter changes are required for all air purifiers. Ultimately, they capture and trap harmful particles, such as mold spores and bacteria.
The filters on some air purifiers can be washed, making maintenance easier. In addition to HEPA filtration, most air purifiers have carbon filters, which must be replaced. Each manufacturer specifies how to replace the carbon filter.
In some modern purifiers, there is usually an indicator light that lets you know when to replace the filters. As a general rule, replace carbon air filters every three months and other filters every six months.
