How much electricity does an air purifier use in different conditions

Recently, air purifiers have been prevalent in both home and office environments. They effectively eliminate the problem of pollutants, dust, smoke, and plant pollen.

However, many people wonder how much electricity an air purifier use and whether it is possible to minimize electricity consumption. These and other questions about air purifiers will be answered in this article.

Generally, most air purifiers consume between 30 to 250 watts per hour, which translates to an average of 0.03 to 0.25 kWh per hour of use.

For example, a small air purifier with a power rating of 30 watts used for 8 hours a day would consume 0.24 kWh of electricity per day, while a larger unit with a power rating of 250 watts would consume 2 kWh per day if used for the same duration.

    How much electricity does an air purifier use and whether its use is justified

    One thing can be said clearly – the use of air purifiers’ power consumption is justified and, in addition, they do not cost a small fortune. The entire cost of running energy efficient air purifier depends on the unit you choose and how you use it.

    air purifier

    Some air purifiers can consume up to 550 kWh of electricity per year with constant use. However, if you use them for longer periods, they can consume a lot of energy.

    As mentioned earlier, the most common air purifier uses 334.49 kWh of electricity per year, counting on 16 hours of dyno and 8 hours of standby per day. It is generally accepted that this is an adequate price to pay, which is reflected in the amount of electricity consumed.

    Typically, people use their air purifiers for about 2 hours a day. To calculate the cost of running air purifiers under discussion, you need to know the following characteristics:

    1. The reference consumption of energy-efficient air purifier is under discussion (in watts).
    2. The cost of electricity per kWh.
    3. The running time of the air purifiers is under discussion (in hours).

    These parameters will help you calculate the cost of the electricity bill consumed to the last cent.

    What is a CADR in an air cleaning system

    The sprayed space that air purifiers can treat is called a CADR. It is measured in cubic feet per miniature (CFM). The CADR of gadget can be a key performance indicator and determines the lifetime performance of air purifiers.

    The ratio of CADR (clean air rate) to Watt (control usage) can be a valuable way to decide which gadget under discussion is most effective in terms of viability. The higher the CADR/W, the more energy-efficient air purifiers are.

    This means that air purifiers can take on more dust from the air with less energy consumption. 4.6 is the normal air purifier CADR per watt, and 2.5 is the most common.

    A purifier’s clean air transfer ratio (CADR) ranges from 0.9 to 14.8. Air purifiers help remove smoke and dust from the air. When the price rises, depending on the gadget, their CADR/W proportions tend to vary.

    Smoke purifiers and their features

    Let’s look at this category separately to get an idea of the lifetime performance of each. The typical CADR (clean air supply rate) per watt of smoke purifier is 4.4. The most common CADR/Watt is 2.5.

    The clean air delivery ratio (CADR) of a smoke cleaner can be an indication of how well it decontaminates the air and ranges from 1.9 to 14.8. The most energy-efficient air purifier for smoke is the Powermatic PM1250.

    It can be found on retail sites at very reasonable prices. This smoke air purifier has the most remarkable CADR/Watt rating of 14.8. This makes it the most economical smoke cleaner. In addition, this unit has the highest CADR/W rating for dust and cleanliness.

    Thus, it is the most productive air purifier known. This model may not be suitable for everyone, as it is designed for stores and not for home use. Right now, the most viable air purifier for the home is the Blueair.

    This unit is the most practicable in terms of viability, with a CADR/watt of the smoke of 13.8. In any case, it is more suitable for home use because of its design and additional features.

    Average bill and amount of electricity used by air purifiers for a large room

    How many watts does a large room air purifier use? Purifiers designed for large spaces usually use the most power. These units can serve rooms larger than 400 sq. ft. Blueair Classic 680I is one of the leading air purifiers for large spaces.

    It is an air purifier spacious room with 698 sq. ft and a surprisingly high 450 CADR rating. At low fan speed, it consumes 15 watts. At high fan speed, it requires 100 watts to operate.

    We will calculate the highest control usage for a 100-watt cleaner by increasing the U.S. kWh rate, which is $0.1319, by the number of hours the cleaner runs. In this case, if the cleaner runs for 24 hours at top speed, it will consume $0.32 per day.

    If you just use it for 8 hours a day, however, it will cost you about $0.11 per day. At low fan speed, the regulator’s consumption is 15 watts and the power consumption is $0.05 per day.

    What is the power consumption of a medium-sized air purifier

    Typically, air purifiers are planned for spaces between 200 and 400 sq. ft. Coway AP-1512HH Forceful is an efficient and well-known air purifier. It is energy efficient air purifier that can cover an area of 361 sq. ft and has the highest control power of 77 watts.

    How much energy does this purifier use per day

    If you use it for 24 hours, it will consume $0.24. That’s $1.68 a week and $7.20 a month. How many watts does a small room air purifier consume? Air purifiers in small rooms are the most efficient to operate.

    For example: let’s take one of the most common Levoit LVH132 HEPA air purifiers. It is supposed to cover an area of 129 sq. ft. This kind of air purifier has the highest control power – 24 watts.

    The energy cost for a small room air purifier is $0.08 per day. Let’s calculate how much energy it uses in a:

    • a week: $0.56;
    • month: $2.40;
    • year: $29.2.

    Air purifiers use exceptionally little energy to operate, which makes them exceptionally energy efficient.

    Principle of CFM in an air purifier

    The CFM represents the number of cubic feet per minute that a filter can take in. It is important to pay attention to the CFM because it determines how fast the filter can clean the air in the room. The CADR number usually contains the classification of the filter.

    CFM is not the same as energy efficiency. The most accurate measure of a filter’s efficiency is the CADR per watt. If you are looking for an air purifier that can clean a large amount of air, you should look for a filter with a high CFM.

    CFM air purifier can be compared to a cleaning machine, which uses a powerful flow of air to get rid of dirt and dust from the surface.

    What is CFM air purifier

    A typical air purifier has a CFM of 209.4. The most popular CFM air purifier is the 450. CFM purifiers can clean the air in a room up to 450 sq. ft. The amount of air that passes through the filter during cleaning depends on the amount of smoke, dust, and dirt being removed.

    The higher the CFM, the more air is filtered. The standard CFM for smoke control is 201.63. The best CFM is 450, and the cheapest CFM is 48. The CleanForce MEGA1000 can be a high-energy efficient air purifier with a CFM of 600. At 88 watts, the power consumption is not high.

    An example of an energy-efficient appliance is the Blueair home air purifier with smoke absorption.

    The CFM for clean removal is often 203.71, but the most common and lowest CFM are 400 and 50, respectively. With a powerful 432 CFM, HP980 Diffuse Nebula is one of the most effective cleaners and smoke removal. 

    The most effective appliances for dust removal have a CFM of 450, a typical CFM of 222.73, and the lowest at 50.
