Common scenarios
Filter and electricity cost checks
Each example adds entered replacement-filter cost to electricity for one year. Purchase price, shipping, tax, accessories, and repairs remain separate.
Optional equipment check
Use the annual filter quantity and cost to compare air purifiers by exact replacement-filter model, filter stages, CADR, room rating, interval, availability, noise, energy use, and whether genuine or compatible filters meet the device requirements.

Result summary
Quick answer
With the sample inputs, this calculator returns $121.54 per year. Yearly filter cost: $90.00. Multiply filter cost by the number of replacements per year, then add electricity cost from average watts, daily runtime, 365 days, and the entered kWh rate.
This is recurring annual cost
The result adds replacement filters and estimated electricity for one year. It does not include the purifier's purchase price, tax, shipping, accessories, repairs, or financing; add those separately when comparing first-year cost.

Calculation details
Formula and methodology
See the exact math used to produce the result.
Annual cost = filter cost multiplied by filters per year plus average watts divided by 1,000 multiplied by hours per day, 365, and electricity rate.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The result combines only the entered replacement-filter expense and electricity use. It does not include the purifier purchase price, shipping, tax, prefilters or accessories not included in the filter cost, repairs, or changes in filter life from actual conditions.

What to verify before acting
Compare the recurring total only after confirming the exact replacement-filter model, realistic replacement interval, intended fan speed, and electricity rate for each purifier being considered.
When to use this calculator
- Comparing annual filter and electricity costs for two purifier options
- Estimating the recurring budget for one room purifier
- Testing how 24-hour operation changes electricity cost
Tips for better estimates
- Confirm that the entered price matches the exact replacement-filter model.
- Keep filter cost and electricity cost visible instead of comparing only one total.
- Update the estimate when the planned fan speed or runtime changes.

How this estimate was built
This page adds annual replacement-filter cost to estimated annual electricity from average watts, daily runtime, and the entered kWh rate. Purchase price, tax, shipping, accessories, financing, and repairs are not included.
Worked example
Example inputs: Filter cost: $45; Filters per year: 2; Average watts: 45 watts; Hours per day: 12; Electricity rate: $0.16 /kWh. With those values, the calculator returns $121.54 per year. Estimated annual air purifier ownership cost is about $121.54.
Air purifier recurring annual-cost examples
| $30 filter twice yearly; 25 W for 12 hr/day | $77.52 per year |
|---|---|
| $45 filter twice yearly; 45 W for 12 hr/day | $121.54 per year |
| $60 filter twice yearly; 75 W for 24 hr/day | $225.12 per year |
| First-year planning | Add the purifier purchase price, tax, shipping, and accessories separately |
Example scenarios
- Enter the price for the complete filter set replaced at one interval, not the purifier purchase price.
- Use the replacement count expected in one year for the room and fan schedule you plan to use.
- Use measured or product-specific watts for the intended speed when that information is available.

FAQs
Air Purifier Annual Ownership Cost Calculator questions
Does this include the price of the air purifier?
No. The result is a recurring annual total for entered filters and electricity. Add the purchase price separately if you need a broader ownership comparison.
Should I use maximum or average watts?
Use watts that represent the fan speed and schedule you expect to use. A maximum rating can overstate electricity cost if the purifier normally runs at a lower setting.
Can I lower the result by extending filter replacement?
The calculator prices the interval you enter; it does not determine when a filter should be replaced. Check the product's guidance and condition indicators separately.

Common planning mistakes
Using the purifier purchase price as a filter expense, assuming a maximum wattage represents every setting, omitting the replacement count, or treating the annual total as a measure of air-cleaning performance.
