Energy Efficient Air Purifier Buying Guide

Here are some key factors to consider while buying energy-efficient air purifiers:

Fan:

Models with a wide speed range should be your priority. Powerful airflow is required for rapidly cleaning a big area, while a calmer fan is suitable for sleeping inside the bedroom. An oscillatory action can indeed be advantageous for covering a greater area.

Apps For Wi-Fi with Remote Controls:

Although having a controller might be pretty helpful, not all versions have it. Some versions may be managed via a mobile phone app and are compliant with a Wi-Fi network. This is an alternative to utilizing a remote. Certain models additionally allow users to view the air purifier’s data collected, allowing users to see which contaminants have indeed been removed.

Automatic Surveillance:

Ensure your purifier has an automated control monitoring feature to identify pollutants in the room. Small particles are detected by an infrared detector, which changes the air purifier’s speed accordingly.

Portability:

Air purifiers are frequently extremely substantial in weight. They can easily exceed 10 kg in weight. Using tires and grips can make moving easier.

Consumption Of Energy:

Like all appliances, air purifiers demand varying amounts of energy to operate. Because air purifiers need to run continuously, you should think about your utility expenditures before acquiring one. Air purifiers need between 50-200 watts of power to function effectively. So get one that consumes the least amount of energy.

Filter Replacement:

If you’re thinking about buying an air cleaner, figure out how much it will cost to replace your filter. The usage and your air quality may determine the lasting of filters. A filter’s average lifespan is around 2000 hours. Therefore, you should replace the filter every 7-8 months or when the LED replaces the filter.


What Is the Most Efficient Air Purifier?

Hard to answer as the most efficient air purifiers are usually not the best in performance, so you need to take the middle way – efficiency and performance.

Levoit is a brand you can trust for the most efficient air purifiers. They are Energy-star certified. They come with HEPA filtration. The sleek design, modern fit, and smart controls make such air purifiers truly efficient. To pick the efficient air purifier, dive in to have a look at some of the features:

  • First, indicate the areas in which the air purifier will be used.
  • Next, determine whether the air purifier must be operated in multiple rooms simultaneously.
  • Depending on how filthy your neighborhood is and how much your air feels difficult to breathe, determine whether you need to operate the air purifier all of the time or not.
  • Choose an air cleaner that covers a small or slightly larger area than the area per room for which you require a purifier.
  • Consider purchasing an Electricity Star-rated air purifier that uses 10-20% lower energy than air purifiers with the same ratings.

Why Should I Need Energy Efficient Air Purifiers?

Regardless of the fan setting, air purifiers cannot reduce a room’s temperature. Instead, explore why you might purchase high-efficiency air purifiers if you would like to save money on your energy bill. Such air purifiers, which ENERGY STAR has approved, can save up to 40% on energy usage.


How Much Money Can I Save Using Energy Efficient Air Purifiers?

Air purifiers that have ENERGY-STAR certified use over 25% less energy than regular devices, saving users roughly 120 kWh per year and $15 per year on power bills. Throughout its lifetime, these savings might total $120!


Are All Energy Star Rated Air Purifiers Energy-Efficient?

Yes, all air purifiers with an energy star rating are energy efficient. Air purifiers earned the Energy Star label are 40% greater energy efficiency, sparing consumers $25 per year on their utility expenses. Over its lifespan, these savings might total $200 or even more! Most air purifiers use about 15-30 cents of electricity every day.


FAQs:

How Much Does It Cost to Run an Air Purifier All Day?

Most air purifiers that run continuously spend between $0.05 to $1.00 every day. This equates to approximately $0.35 and $7.00 each week.

We’ll examine the power consumption for small, medium, or large air purifiers in the following three cases. The simple calculations are as follows:

Large room air purifiers at 100 W approximately costs between $0.24 to $0.40 per day

A medium-sized air purifier at 77W approximately costs around $0.24 each day.

A small-sized air purifier at 28W costs just under $0.10 each day.

Are HEPA Filters Energy-Efficient?

HEPA filters are less energy-efficient compared to air purifiers that feature smart technologies. So, if you are seeking something that is more energy-efficient, opt for HEPA filters.

Do Air Purifiers Use a Lot of Electricity?

No, most air purifiers don’t consume a great deal of electricity. They are classified as one of the modest loads which can run continuously without significantly increasing electric bills.

Air purifiers are similar to fans. However, they don’t utilize a great deal of electricity when they’re running, drawing roughly 1 kilowatt-hour on average, thus costing approximately 15 cents each day, based on their rating and energy rates.
