"Getting a breath of fresh air" isn't a mere pleasantry. The saying started as a reminder for 18th-century factory workers to take a break from their poorly ventilated facilities. That's because whole house indoor air often contains more dust, particulates, and pollutants than outdoor air that can cause allergies.

The Honeywell F100 has a full cabinet that measures 18 inches by 26 inches. The whole house air cleaner has a steel frame for long-lasting durability and an energy-efficient door. Thanks to an improved gasket, you can reduce 37 percent of air loss through the door.
When it comes to cleaning and removing indoor air pollution, the Honeywell F100 uses a MERV-11 filter. These are similar to whole house HEPA filter models but do not have standardized values between brands. The rating system goes from 1 to 20, with higher numbers more effectively filtering the air in your home with the use MERV-11 filter.
The MERV-11 is best-suited for trapping larger particulates in your house, like dust and pollen. Also, the MERV-11 filter is 92 percent effective at trapping matter at least 3 microns in diameter. Smaller particles are more challenging to capture, though, when using a MERV-11 filter.
Overall, the Honeywell F100 with MERV-11 filter is best for pet owners or families on a budget. The unit won't ding the wallet like other indoor air pollution cleaners and makes a discernible difference in overall air quality.

The Oransi Air Purifier uses a three-stage filtration system: a pre-filter, a v-HEPA filter, and an activated carbon filter. As air circulates through these extended media filters, different particles get stuck at different stages. For instance, the v-HEPA filter collects 98 percent of matter, while the activated carbon filter targets gases.
Many of the best whole house air purifiers have activated carbon filters. The panel uses a bed of charcoal to remove unwanted odors through filtration, which is known as a charcoal filter. The activated carbon filter cannot trap dust particles or pollen, though, which is why Oransi includes the two additional stages. Each filter will last for a year, though the company recommends cleaning them every two to three months.
This whole-house air purifier gives owners significant fresher air without the price tag of top-end models. You get the benefit of many smart features, like an air quality monitor that automatically adjusts the fan speed to ensure maximum cleanliness.

What You Need to Know Before Buying a Whole House Air Purifier
How Does an Air Purifier Work?
Americans spend $250 million on air purifiers (1) each year, so it's worth taking a second to cover how they work. Most models use a rudimentary air filtration system to clean the air. Some other versions use ionization, electrostatic shock, ozone generation, and UV light to have an efficient air purifier.
An air purifier with a filter circulates air around the house. When the air flows through the device, the filter traps particles that are invisible to the naked eye. Pleated air filters work best because they have a large surface area to capture unwanted matter, which is why pleated filters are one of the most common air filters used in large homes.
The best whole house air purifiers can trap particles three microns or smaller. That is the same as snagging a piece of dust one-tenth the width of a human hair. This technology is also present in your home's HVAC system but is typically not as good at capturing these small particles.
How Much Does an Air Purifier Cost?
The short answer is: it depends. The cost of an air purifier varies based on its features, size, brand, and more. For instance, an air purifier with a High-Efficiency Particulate Air (HEPA) filter will likely cost more than a model without one. True HEPA filters are often a sign of a high-quality product.
Similarly, the size of your home will dictate the size of your air purifier. The more square footage you have, the more powerful the air purifier needs to clean the whole house. All things considered, you can expect to spend anywhere from $75 to $800 for a home air purifier.
What Is a HEPA Filter?
A HEPA filter can capture airborne particles as small as three microns in diameter, such as mold spores. The pleated filter uses a multi-layered netting of incredibly fine fiberglass threads.
HEPA filters capture particles large and small. The filter traps larger particles through direct impact with the fiberglass threads, while medium and small particles become stuck due to interception and diffusion.
A HEPA air filter will remove 99 percent of particles that are 2 microns or smaller. Meanwhile, a True HEPA air filter has an efficiency rating of 99.97 percent.
Benefits of a Whole House Air Purifier
Improved Air Quality
According to the EPA, indoor air quality has two to five times more pollutants than its outdoor counterparts. In some cases, indoor air quality is 100 times worse (2), which is especially concerning because we spend 90 percent of our time inside the home. Being proactive about cleaning your airflow by avoiding harmful pollutants can make a world of difference when it comes to your overall health.
Homeowners with poor ventilation and air quality levels are more prone to various health conditions and food contaminants. These include, but are not limited to, allergic reactions, headaches, eye irritation, and coughing. Some people may experience severe respiratory issues that aggravate their asthma symptoms or suppress their immune system because of gaseous pollutants like indoor air pollutants.
The best whole house air purifiers will remove these potentially harmful airborne particles regularly. Whether that is dust particles, allergens, pet dander, bacteria, or contaminants, the purifier will leech them out of the air. That way, you and your loved ones can breathe easily again and avoid allergies and air pollution.
Removes Unwanted Odors
Believe it or not, the best air purifiers can make your entire house smell better, too. The air filters can remove pet odors, cooking odors, cigarette smoke, and other unpleasant smells through the use of an activated pre-filter. This feature is especially useful for people who live with smokers and want to reduce their risk of second-hand smoke inhalation.
Discreet and Portable
After you install your whole house air purifiers, you'll probably forget it's there. Many portable units of air purifiers are compact, easy to carry, and fit snugly in the corner of a room. Plus, they make less sound than your average house fan, so you shouldn't be bothered by noise pollution.
Furthermore, most models are a breeze to set up. For instance, all you have to do for the Alen BreatheSmart Classic Customizable Air Purifier is put in an air filter and turn on the unit. For other air purifiers, like the Aprilaire 2410 While-Home Air Cleaner, a contractor will connect it to the HVAC system on your behalf.
What to Look for in the Best Whole House Air Purifier
What makes one home air purifier better than the other? That's the million-dollar question. Generally speaking, the best whole house air purifier is the one that serves your needs and preferences. Here are a couple of factors to consider when buying a home air purifier.
Clean Air Delivery Rate (CADR)
AHAM (Association of Home Appliance Manufacturers) invented a measurement called the Clean Air Delivery Rate (CADR.) The figure evaluates how effectively an air purifier removes specific particles from the air to prevent allergy symptoms. A CADR rating will also tell you how quickly the air purifier cleans a room.
Each CADR rating looks at how efficiently the home air purifier removes smoke, dust, pet dander, and pollen because these pollutants come in various sizes. Smoke particles are up to 0.3 microns, dust is up to 3 microns, and pollen is up to 11 microns. Some of the best whole house air purifiers have CADR ratings of upward of 400.
The larger your home, the more powerful the air purifier should be. You should also consider where the whole house air purifier will go. The room you place it in will dictate overall circulation and air cleaning quality. It is also necessary to have a return air duct to every single room you have if your home has rooms that are either too hot in hot weather or are cold in cold weather
You should also measure the total square foot coverage area in your home. The easiest way to do so is to look at your house's paperwork or floor plan. If you don't have that, you can multiply the outside length and width of the walls by the number of levels or measure the dimensions of each room and add them to get the total square foot coverage area.
The last step is to match the total square footage to the home air purifier specifications. If your house is 3,500 square feet, you want a whole-house air purifier close to or slightly above that number. If you cannot find a device in your price range, you may have to compromise.
A True HEPA air filter is the gold standard when it comes to removing fine particles from the air. The efficient HEPA air purifiers can filter 99.97 percent of particles with a diameter of 0.3 microns or greater. Keep in mind that there are no synonyms for a HEPA filter. Companies that use the terms "HEPA-type" or "HEPA-like" are typically using marketing to make their air purifiers appear better than they are.
As we mentioned earlier, there are other types of air purifiers besides those that use filters. Ionizers and ozone generators produce ions and ozone, which both have a charge. Because airborne particles are neutral, the ions and ozone attract them and drag them to the ground.
Electrostatic filters use a similar mechanism as ionizers and ozone generators. This type of home air purifier charges the particles in the air before trapping them in the machine, which also changes the airflow. You can later remove the filter, clean it, and reuse it.
The final type of purifier is UV light. You can install UV lights in your HVAC system as a way to kill unwanted bacteria, microbes, and even viruses. The addition is one of the best ways to ensure germ-free air flow at home.
When you buy a whole house air purifier, the upfront cost is only one portion of the payment. Depending on the make and model, there are other potential expenses. The two most notable hidden costs are maintenance and energy efficiency.
Every home purifier with a filter like HEPA and MERV filters will need a replacement. The only question is when. All else equal, a whole house HEPA filter will likely last you longer than a MERV filter. Similarly, some larger units require you to replace the whole filtration system, while others allow you to replace them incrementally.
Beware of companies that require you to buy filters like a MERV or a HEPA filter to maintain the warranty. The system can keep homeowners captive for years because not paying likely means getting a new home air purifier. Make sure to calculate the cost of maintenance, including the needed filters like MERV, before purchasing.
If you opt for an electronic whole-home air purifier, you will also want to consider energy usage. Look for units with Energy Star approval ratings and lower overall wattage. Some of the best models even have eco-friendly modes that convert to stand-by operation when the sensors no longer detect pollutants.
AHAM develops standards to ensure home care appliances are safe and effective. That includes whole-house air purifiers. The system creates an easy way for consumers to assess the quality and safety of an air purifier. While the program is voluntary, most reputable brands make sure to get the AHAM seal of approval.
