If you have decided to purchase an air purifier, keep in mind that the initial cost of purchasing it is not the last investment.

To understand how to determine an energy-friendly air purifier model, it helps to know how it operates. Most air purifiers run on electricity, most use filters, and if the air purifier crashes down, you will need replacement parts. Over time, these costs can add up. It’s good to study all of these factors before you make your final choice.


Alen BreatheSmart FIT50, Costs of Air Purifiers

There are air purifiers without filter costs but let’s be real here. The best air purifiers are those with filters. And if an air purifier has a filter, then you will have to clean it (if possible) or replace it.

Don’t only look at the price; see also filter’s life. And don’t trust manufacturers. They are usually adding several months extra, similar to car sellers state fuel consumption.

For example, air purifiers for general air quality – Fellowes AeraMax 200 and Winix P300. They both have carbon pre-filters and True-HEPA filters. But filters cost per year is $46 versus $70.

  • Allergy air purifiers filters cost example

IQAir HealthPro Plus and Alen Breathesmart.

Both can cover more than 1100 square feet of large spaces. Both are of excellent quality and are powerful. We calculated filter costs per year.

IQAir HealthPro Plus filters cost between $145 – $270 (depends on your indoor air quality – how often you will replace them)

Alen Breathesmart filters cost between $59 and $109 (depends on the filter model you choose – HEPA-pure, HEPA-silver, HEPA-OdorCell, or HEPA-FreshPlus filter).

You can see that even with the most expensive Alen filter, you pay much less than with IQAir.


Energy Costs of Air Purifiers

Energy used by an air purifier is another important thing you have to consider. Here are a few things you have to keep in mind – air cleaner energy usage (watts), how regularly it will work, and how many fan speeds it has.

  1. Watts. This is usually stated in the user manual and on the air purifier.
  2. Work time. Maybe you have read that you have to run an air purifier only for 1 hour, and it will clean the air. Yes, it will mostly, but new pollution particles twist in the air almost all the time. So you have to turn it back on after a while to keep your indoor air clean. Usually, you will keep an air purifier on for between 8 to 10 hours per day.
  3. Why are fan speeds important? For example, the air purifier has 4 fan speeds; then, it will clean your room fast with the biggest fan speed and consume the most energy. With the lowest, it will consume a meager amount of energy, but you will have to run it 24/7 to clean something.

Ok, I like examples, so let’s take a look at the top 5 best allergy air purifiers energy consumption and how much it will cost.

They all are powerful, so to keep it simple, let’s say they work 365 days a year 8 hours per day. 1 kilowatt-hour (kWh) cost 12 cents.

IQAir HealthPro Plus consume 215W max. That’s $6.28 per month, $75.38 per year.

Haverhill HAP52010E consumes 60W max. That’s $1.75 per month, $21.03 per year.

Alen Breathesmart consumes 105W max.  That’s $3.06 per month, $36.81 per year.

Whirlpool Whispure 510 consume 39W max. That’s $1.13 per month, $13.67 per year.

Blueair 403 consumes 120W max. That’s $3.50 per month, $42.07 per year.

You can easily calculate how much your air purifier will cost you—multiply kilowatts with 1 kilowatt-hour (kWh) cost with days. For example, The air purifier consumes 200kW. Cost = 0,200 x 0,12 x 8 (hours per day) x 30 (days) = $5,76 per month.
