The first entry on our list is a very small but powerful device that can purify rooms up to 500 square feet. It features a true HEPA and activated carbon filter and can trap debris 0.3 microns small. 0.3 micron sized debris is the size range that 90% of sinus irritants lie in. 

If that wasn’t enough, the Silver Onyx also has a UV sanitizer to eliminate germs in the air too. All in an appliance that you can easily set on the floor, desk, or counter top.

The Silver Onyx Air Purifier has a 5-stage cleaning system. The pre-filter takes care of pet hair and larger pollutants, while the HEPA H13 activated carbon filter removes finer particles from the air. The UV light and ION generator round out the cleaning process by taking care of odors. 

With it’s five speed setting and automatic mode, you have plenty of options when it comes to air purification. The Auto mode will analyze the quality of air and adjust accordingly, this helps with keeping things as efficient as possible. Running at full speed, the Silver Onyx consumes only 24 watts of power, thats an average of 9$ per year, when run 8 hours per day.  

A built-in indicator alert lets you know when it is time to change the filter, which lasts about 6 months with regular use.

Trial Results

Despite its small size, this air purifier is great at providing clean air. With the fan setting on low it is quiet and efficient, with a noticeable difference in air quality within an hour. For rooms smaller than 500 sq. ft., this is one of the best budget air purifiers you can get. 

The Blue Pure 211+ is our favorite air purifier on the list. It’s very quiet and does not draw a lot of power, it has a very streamlined design, and the pre-filter comes in a variety of colors. This particular model is rated to purify air in rooms of up to 540 square feet and does so quickly and quietly. It also features a washable outer mesh pre-filter for trapping larger debris and is very popular for those who live in areas with wildfire smoke.

With it’s one button control, you simply tap the white circle on the front and it turns on, while each subsequent tap raises the fan level from low-medium-high. With these easy-to-use and intuitive controls, anyone can operate this machine. The only drawback is if you have pets that sometimes walk into it, shutting it off! 

When it is time to change the filter, the ring around the light changes color to let you know. The filters within are collapsable, which makes them easy to store and to replace you simply lift off the top half of the device and pull out the filter.

At high the sound is loud but still a reasonable 51dB. Running at low it is hardly noticeable and great for overnight use.

With its outer pre-filter that comes in a variety of colors, you can dress this filter up to fit your aesthetic. Easily removable, simply wash it, let it dry and put it back on. Within the Blue Air 211+ is a collapsable filter that uses electrostatic filtration to remove up to 99.97% of airborne particles, with a layer of activated carbon to filter out smelly household odors.

  • Eliminates most pollutants that cause sinus irritation and allergy issues
  • A variety of colored pre-filters to choose from
  • One of Wirecutters top-air purifier picks


  • Filter replacements are expensive
  • Not WIFI capable 

Trial Results

Having used the Blue Air 211+ during wildfire season, there was a direct and noticeable difference an hour after turning this on. We went from sore throats, sneezing, and itchy eyes, to normal life, very quickly. Running this 24 hours a day at the lowest setting, you soon forget its even there. When ran at higher settings, mostly when the cats use the litter box or we are cooking up a storm, the air is cleared quickly and the volume isn’t so loud that you can’t have a conversation.
For the price, this is an amazing air purifier. It looks sleek and modern, especially with the different colors that the pre-filter comes in. Customer service is spot on and quickly returns any inquiries, as we wanted to know if it filtered wildfire smoke (it does). This is a great purchase for the home and a good middle-ground between the two other air purifiers on our list. 
The Winix 5300-2 is a great air purifier for the price. Using a True HEPA filter, it removes dust mites, pet dander, pollen, and other air pollutants in rooms up to 360 square feet. While this air purifier lacks a remote control, it does have an Auto-Mode which works in conjunction with its Smart Sensors. This setting will adjust the fan speed to accommodate the level of pollution in your home, reducing your need for hands-on fine tuning. 

The fan has four speeds, with low being quiet and turbo mode offering quick filtration. 
 In Sleep Mode, this device automatically adjusts the fan speed and light level of its display, allowing for uninterrupted rest.  


  • Rated for coverage of spaces up to 360 sqft.
  • Four adjustable fan modes, as well as an auto and sleep mode.
  • Filter replacement indicator will light up when the HEPA filter reaches the end of its lifespan.
  • Inexpensive


  •  No remote
  • Can not disable sleep mode

Trial Results

The Winix 5300-2 worked really great at reducing smells from cooking and allergy related issues. While it will not work as well in larger rooms, if you are using this in a kitchen, office, or bedroom, it will get the job done. Sleep-mode is a great idea and offers a quiet, lights-out option, but we found that the fan speed was too low. The sensors are very sensitive and quickly changed to “red” while we were cooking, and within 45 minutes had greatly reduced the smell of frying fish in our home. Typically we had it running at speeds 3 and 4, because this was a good middle ground of sound vs. strength. For the price, this is a great option. 

How Can an Air Purifier Help with Carbon Monoxide?

Carbon Monoxide is an odorless, colorless gas that is extremely dangerous in high quantities.  Levels of carbon monoxide can increase during processes that burn fuel, such as wood fires, running car engines, water heaters, and other household appliances. 

An air purifier is the most reliable method for truly removing pollutants from the air inside your home.  These multi-level air purifiers provide different levels of filtration in each layer, meaning they remove and reduce a greater variety of potentially harmful particles, gases, and bacteria from your home.

What Should I Look for in an Air Purifier for Carbon Monoxide?

In order to effectively remove carbon monoxide, the air flow of the purifier you choose must be appropriate for the size of the room you intend to use it in.  Measure your room, and double check the layout to ensure your air purifier isn’t obstructed by furniture.

A true HEPA filter will help remove any particulates related to carbon monoxide production, such as smoke or debris, while an activated carbon filter will help reduce the gas particles.  Be sure to read the specification for any air purifier to learn more about its filtration system and the particles it can capture and reduce in your environment.

Frequently Asked Questions

I have a carbon monoxide detector. Do I need an air purifier for carbon monoxide?

Carbon monoxide detectors do not have a filtration device that can clear the air- they only provide a reading of harmful carbon monoxide levels.  An air purifier contains one or many filters that will remove pollutants from your home.

How often should I run my air purifier for carbon monoxide?

Most home air purifiers were designed to be run continuously, as dust and odor particles are constantly present within your home.  Many newer air purifiers feature automatic cycles or a real-time sensor that can adjust the fan speed based on air quality readings, improving the efficiency of the device while decreasing your home energy bill.

Final Thoughts

Keeping the air free from allergens and pollutants is a priority for all homeowners.  Choosing an air purifier can help you create the freshest, cleanest environment within your home.
