Energy Efficient Air Purifiers

Air purifiers help keep your home clear of harmful indoor air pollution and allergens. But while they need to be effective, they also should be energy efficient when providing better indoor air quality.


What Do We Mean by Energy Efficiency?

While it might seem obvious, the idea of energy efficiency has become so much a part of our regular lexicon that it’s become a bit misunderstood. Energy efficient can be defined various ways, but the best definition would seem to be something that uses little energy while still getting the job done.

“Efficient" is the part that sometimes gets confused. Efficiency does not mean using less energy; it means getting the most from whatever energy is being used. Efficiency can be defined as the ratio between the work being produced and the energy being put in.

If nothing else, remember this: efficiency is a ratio between the results and the total energy used.

For a vehicle, the efficiency ratio is miles per gallon. The miles traveled are the result and the gallons are the total energy.

With air purifiers, the primary goal is to provide clean air while using as little electrical power as possible. If the air flow is too low, the air purifier will be ineffective and won’t remove the desired amount of pollutants. If it uses too much power, it will also drive up energy consumption.

The goal, therefore, is to strike a balance between the removal of particles and the usage of energy. With quality designs, engineering, and parts, this can be achieved.


CADR: The Starting Point for Energy Efficiency

The total performance of an air purifier is described by a measurement called the Clean Air Delivery Rate (CADR). Created by the Association of Home Appliance Manufacturers (of which we are proudly a member), this is the industry standard that was created to give consumers a consistent gauge for understanding air purifier effectiveness.

All air purifiers in this program are tested at an independent third party lab under strict test controls to ensure validity.

This becomes extremely helpful for comparing two different products. The rating looks at how effectively air purifiers remove a variety of particulate sizes and they are represented as smoke, pollen, and dust.

Also, the system of measurement was designed for portable air purifiers that clean the air in a smaller room, and it may not be a useful gauge for larger systems, such as air purifiers used for commercial buildings. The CADR remains an important tool for comparing the effectiveness of air purifiers.


Watts: The Next Important Measurement

While electricity can be a fairly simple concept, there are a lot of different terms that become involved when researching electrical consumption. Volts, amps, current, and resistance are all part of understanding electricity, but for the sake of this conversation, we will stick to one term: watts.

Watts are simply the measurement of electrical power. We won’t drag this article down with an in-depth discussion of electrical systems, but you can essentially think of watts as the amount of power provided by electricity. If you think of electricity running through a wire as water running through a river, the rate of current flow is the amps. Water, like electricity, can provide power to turn a mill. In this case, the power of electricity is our watts.

If nothing else, just remember that the higher the watts, the more power the machine is using.


CADR to Watt: The Next Step in Measuring Efficiency

Okay, now lets combine the two. If you want to have an energy efficient air purifier, you need a unit that uses less power but still provides active filtration. This means the output (CADR) is compared to the energy consumption (watts).

When looking for a high-quality air purifier, you want to seek a machine that has a high CADR-to-watts ratio. The more output you have for every watt used, the more energy-efficient your machine will be.

OV200 Air Purifier

  • 60 Watts
  • Room coverage: 400 square feet
Ov200 air purifier in bedroom

This is a lower priced air purifier that gives you efficient operation while allowing you to remove many of the air pollutants that can be found in indoor air. One of the reasons this unit is so effective at air purifying is that it only uses 60 watts of energy while effectively filtering over 99% of all particles and allergens that come through the machine. It uses multiple technologies to achieve this result, including a top-quality motor that is not only powerful and efficient, but also quiet while in operation.

This small air cleaner is designed to remove dust, air pollution, and allergens in areas such as a bedroom. It has a sleek profile that allows it to be placed conveniently in virtually any room, even small bedrooms or crowded dorm rooms. It measures only seven inches in depth, so it can be placed against a wall and won’t take up a lot of your already limited space. Thanks to the efficient operation, this air purifier can be used to clean the air in rooms measuring 400 square feet.

One of the most important aspects of having an efficient machine for air purifying is being able to set the machine to the right levels and speeds. With the OV200, you can utilize three different speed settings to get the right output, and energy consumption, when you need it. It also has four timer settings, so you can program the machine to run for one, two, four, or eight hours; once the timer is up, the air purifier will turn itself off automatically. There is also a night mode, which reduces the fan speed to the most quiet level, and turns the displays off so they don’t add too much light to your bedroom. The kid lock setting also allows you to lock the purifier at a specific speed so curious and active children can’t accidentally change it.

With these settings, as well as an efficient motor, this is one of the most energy-efficient air purifiers you can have in your home.


Max HEPA Air Purifier

  • 90 Watts
  • CADR Rating: 230
  • Room Coverage: 600 square feet
Max energy efficient air purifier in living room

By using only 90 watts of energy for air purifying, the Max HEPA air purifier is able to achieve a high level of performance without a massive increase in your energy consumption. While there are many aspects that make this machine so efficient when you need to purify the air, one of the most important is the V-Lock/V-Seal system, which ensures that no air is allowed to by-pass the filtration system. Essentially, any air that comes into the purifier is filtered, meaning the machine gets the most effective results from every bit of energy used.

The machine also has different filters for different purposes, maximizing its effectiveness at air purifying. The filtration starts with a pre-filter, which removes the largest airborne particles, such as large specs of dust. To increase the value, this filter is durable enough to be vacuumed lightly. The next stage is a v-HEPA filter, which removes many of the smallest particles, including pet dander, mold spores, and pollen. It also has a carbon filter that helps remove air pollution and light odors.


Tips for Increasing Home Energy Efficiency

An efficient air purifier is an important tool for your home, but there are many strategies you can use to increase your home’s efficiency. Best of all, some of these strategies also increase your air quality!


Use a Whole House Fan Instead of the A/C

A whole house fan can be used when the air outside is warm, but not extremely hot or humid. Mounted in the ceiling above the top floor of the home, these fans pull air through the house and into the attic, creating ventilation the makes the home more comfortable. By cycling air, these appliances remove many of the harmful indoor pollutants, including VOCs released by certain products, as well as dust that can be floating in the air.


Use the Sun Strategically

You don’t have to have a solar panel to take advantage of the sun’s warming power. During the winter, when you are trying to warm the house, open the shades and allow the sun to shine in. This will create a basic greenhouse effect that warms the house, and it will allow your furnace to work a little less harder to warm your home.


Look for ENERGY STAR Appliances

The ENERGY STAR program was created by the EPA to provide reliable information on energy-efficient products. If you see an ENERGY STAR label, you know you are getting a product that has been independently certified for maximum efficiency. You can find windows, furnaces, washing machines, heat pumps, and other products with the ENERGY STAR label.


Change the Furnace Filter Regularly

Another step you can take to increase the efficiency of your home is to replace the air filters for your air conditioning or furnace system. These filters keep dust from entering the furnace’s interior components, and when they become clogged, it means the appliance has to work harder to pull in air.

Replacement filters not only increase efficiency, they also helps control the quality of air in your home. Air filters are designed to protect the appliance, but by trapping dust and other airborne particles, they also reduce the amount of air pollution in your home, enhancing indoor air quality.


Seal the Vents

A lot of energy to create the ideal temperature is lost through gaps in a home’s ventilation. To go from the heater to the living space, warm air travels through vents, which are usually in or around the ceiling of the basement.

While this air travels through the vents, it can escape through gaps, meaning it doesn’t reach the living space. The thermostat then needs to keep telling the heater to churn out warm air, which of course uses more energy. By sealing the gaps, and insulating the vents if possible, you will significantly reduce the burden on your furnace.


Use Ceiling Fans When Running the Air Conditioner

Instead of constantly running the air conditioner at a high temperature, you can use ceiling fans to create a cooling movement of air throughout the home. According to the National Association of Home Builders, using a ceiling fan can reduce your electric bill by as much as 40% because it creates a draft that makes the room feel cooler. (Although it doesn’t actually cool the room.) With this cooling effect, you can raise the thermostat four or five degrees, which means significant savings during the hot summer months.


Turn Off Lights When Not in Use

It’s an obvious step, but it’s one that’s often overlooked. To increase the efficiency of your home, simply turn off the lights as much as possible. When you leave a room or leave the house, turn the lights off behind you. On sunny days, open the shades and let natural, free light flow into your house.

With all of these steps, combined with an energy efficient air cleaner, you’ll have better energy consumption from your entire home.
