Buyer’s Guide:

Air Purifiers for Odor Removal

Causes of Unpleasant House Odors

  • Smoke

    Cigarette smoke tends to stick on the walls and carpets and linger in the air, making the entire space smell awful and allowing thousands of cancerogenic chemicals to linger in the air and potentially damage your health. A good air purifier for odor removal should help fix this problem immediately, but the best solution would be to not smoke inside these confined spaces.

  • Pets

    No matter how clean you think your pet is, it can still be one of the causes of unpleasant indoor odors. Apart from the air purifier, make sure to properly train your pets and make sure that they are not causing any problems to the upkeep of your home.

  • Sink Pipes

    A clogged sink is what usually causes unpleasant odors to emit from the drainage system. Although a purifier will remove the unpleasant smell effectively, you will still have to get rid of the blockage. In case there are unpleasant smells in rooms like the kitchen or the bathroom, make sure to check the pipes.

  • Cooking

    A room where unpleasant smells are inevitable is the kitchen. The reason why these smells are almost permanent is because most are caused by the foods you cook. Of course, you should not stop cooking just because unpleasant smells will invade the kitchen. Instead, place the device in the room to eliminate them.

Market Leading Air Filter Brands

  • Alen

    Alen is a brand known for its consistent focus on researching and developing new and effective technologies to ensure both reliability and longevity. The manufacturer also offers a lifetime warranty to be of service for consumers for a long time.

  • Honeywell

    Like many brands out there, Honeywell manufactures high-quality products that improve the quality of people’s lives. Best of all, this company does its best to avoid damaging the environment during the manufacturing processes, using “green” methods. If you are looking for a top-notch air filtration system that is going to help you get rid of unpleasant indoor odors, this is one of the top companies we recommend you purchase from as it delivers durable, reliable, safe, and dependable products.

  • GermGuardian

    GermGuardian is undoubtedly one of the biggest names in air filtration systems. The company makes it a point to innovate with every air purifier it releases, creating a healthier, safer and happier environment for users. If you buy a system manufactured by this brand, you will be pleasantly surprised by the wide variety of options it offers.

How We Rated the Filtration Systems

Are you wondering why we ranked the odor removal air purifiers the way we did? This section of the article explains the ratings that influenced our rankings. Knowing more about our rating system will allow you to form a better idea of what you should look for when making this purchase, so do not skip this section of the article.

  • Filter Quality

    For an air purification system to be able to effectively remove unpleasant indoor odors, it must have two distinct features: high-quality filters and activated carbon technologies. The BreatheSmart model features the HEPA-OdorCell, which actually specializes in odor removal and does a superior job at eliminating smoke and other heavy odors, so we ranked this model higher than the others.

  • Maximum Recommended Room Size

    The quality of an odor removal air purification system greatly depends on the surface it can cover. After all, it should be able to handle the clearing of unwanted smells in both small and large rooms. The BreatheSmart system produced by Alen scored the highest when it all came down to purifying the air in a room as large as 1100 sq. ft.

  • Pollutant Removal Efficiency

    For the air to be cleared of all unpleasant odors, the filtration system must be able to eliminate lingering pollutants. As you can see, all of the models featured in our list are capable of removing more than 99 percent of the pollutants and contaminants in the air indoors.

  • CADR Rating and AHAM Certification

    The clean air delivery rate (CADR) rating should be high for a quality air purifier. It is measured in cubic feet per meter (cfm) and detects the smoke, dust, or pollen that is present in the air. The Association of Home Appliance Manufacturers (AHAM) certification is the determinant that measures how good CADR ratings are, and it recommends that devices follow the “⅔ rule.” This rule basically means that the smoke CADR must be equal to or surpass ⅔ of the room area in square feet.

    As you can see, we took into consideration the efficiency of the filters, giving the Honeywell HPA300 higher ratings when it came to this aspect since it can deliver a 100 cfm smoke CADR rating for a 155 sq. ft room, 200 cfm smoke CADR for a 310 sq. ft room, and so on.

  • Energy Star Certification

    Ideally, the filtration system must be certified by Energy Star in order to minimize electricity costs. We chose purifiers with the Energy Star certification because we want you to invest in a product that will meet expectations. Regardless of the model you go choose, you won’t end up paying too much money when the bills come even if it operates through long hours.

Frequently Asked Questions

Can indoor odors present a threat to my health, or are they simply an inconvenience?

While most consider getting rid of unpleasant indoor odors solely for the inconvenience, the truth of the matter is that certain odors do pose a health risk. The perfect example is cigarette smoke odor, which can be caused by fumes packed with 70 different pollutants that can present a danger to your health as well.

How do carbon filters help with odor removal?

The activated carbon filter acts like a sponge that traps the unpleasant odors in the surrounding air. Specifically, it targets the compounds that cause these odors, whether it is from the bacteria from sink pipes or even pet odors. The carbon filters go through the process of adsorption (not to be confused with absorption) wherein the odor compounds are captured and retained. They don’t necessarily eradicate the chemicals, but filters trap an amount adequate to eliminate the odor in the air.

Final Thoughts

If unpleasant odors are a common occurrence in your home, you can get rid of them with the use of any odor removing air purifier presented in this article. Our favorite, though, is the Alen BreatheSmart, a device that caught our attention because of its features and large coverage area. What really made it stand out, though, is its lifetime warranty offer, which is always beneficial for consumers.

If you are on a budget, we recommend you take another look at the GermGuardian AC5250PT. It comes at an affordable price without sacrificing quality, and it is able to effectively remove unpleasant odors using its charcoal filter.
