Now, let's dive deeper into the costs, maintenance, and performance differences.
Disposable VS Reusable Furnace Filters
Purchase Price Comparison
When comparing disposable and washable filters, upfront costs play a big role. Disposable filters typically cost between $10 and $50 per unit, while washable filters range from $60 to $120. Both options come with their own perks. Let’s break down the costs further.
Disposable Filter Prices
Here’s a look at some popular disposable filter brands in 2024 and their features:
| Brand | Features | Price Range |
|---|---|---|
| 3M Filtrete Ultra Allergen | Traps tiny particles like dust, smoke, and smog | $15–25 |
| Nordic Pure AC | Hypoallergenic, with antimicrobial protection | $20–35 |
| Honeywell Home MicroDefense | Improves airflow and energy efficiency | $25–40 |
Now, let’s see how washable filters compare in price.
Washable Filter Prices
Washable filters come with a higher upfront cost. For example, ElectroDust offers a washable filter priced at $107, featuring a MERV 7 rating, electrostatic design, lifetime warranty, and custom sizing.
Price Factors
Several factors influence the cost of both disposable and washable filters:
| Factor | Impact on Cost |
|---|---|
| Size | Larger filters tend to cost more |
| MERV Rating | Higher ratings usually mean higher prices |
| Thickness | Thicker filters are generally more expensive |
| Material Quality | Better materials can increase the price |
These factors help explain the price variations across different filter types.
"Disposable filters are typically known for their superior overall efficiency. In contrast, washable filters usually have a relatively low holding capacity, capturing only up to 75 percent of larger indoor pollutants like dust mites, carpet fibers, and pollen particles. Disposable filters with a MERV rating of 9 to 12, on the other hand, exhibit relatively high retention rates. These filters can capture up to 95 percent of the larger particles circulating through your home, thereby maintaining high indoor air quality and promoting the efficient operation of your HVAC system."
While disposable filters are cheaper initially, washable filters might save you money in the long run.
Total Costs Over Time
Filter Life and Changes
One of the biggest factors in understanding costs is how often filters need to be replaced. Disposable filters typically need replacing every 30–90 days. On the other hand, a well-maintained washable filter can last 5–10 years. This difference in lifespan has a direct impact on long-term costs. To put it into perspective, a single washable filter can take the place of 20 to 60 disposable filters during its lifetime . This shift in replacement frequency significantly affects yearly expenses, as shown below.
Year-by-Year Cost Breakdown
Disposable filters cost about $90 per year, while the upfront cost of a washable filter averages $107 - even if you account for replacing it once after 5 years . The table below breaks down how these costs compare over different timeframes.
Cost Timeline Table
| Timeframe | Disposable Filters | Washable Filter | Savings (Disposable vs. Washable) |
|---|---|---|---|
| Year 1 | $90 (6 filters) | $107 | –$17 |
| Year 3 | $270 (18 filters) | $107 | $163 |
| Year 5 | $450 (30 filters) | $107 | $343 |
| Year 10 | $900 (60 filters) | $214* | $686 |
*Includes one replacement washable filter after 5 years.
Though washable filters require monthly cleaning to keep them working efficiently, the savings over time make them a worthwhile investment. Over the years, the financial advantage of washable filters becomes clear, with significant savings accumulating after the initial purchase .

Upkeep Costs
Washable Filter Maintenance Costs
Washable filters need regular care, which includes removing, washing, and allowing them to dry for 20–30 minutes. Many homeowners opt to keep a spare filter handy to use while the primary one dries. While some choose to use cleaning sprays, the main expense usually comes from purchasing that extra backup filter.
ElectroDust offers a washable filter priced at $107 that includes a lifetime warranty. This warranty can help reduce future replacement costs, making it a practical choice for many. Proper maintenance is key to keeping your system running efficiently, as explained below.
Impact on System Performance
The condition of your filter directly affects how well your HVAC system operates and how much it costs to run. A neglected filter can block airflow, leading to higher energy use, increased utility bills, and even damage to your system that may require repairs.
Running your HVAC system without a filter while the primary one dries can lead to contamination issues. That’s why having a backup filter is so important . Staying on top of filter maintenance not only cuts down on replacement costs but also helps your system perform better, saving you money over time.
Value Analysis
Assessing both performance and waste generation is key when determining the overall value of your filter choice.
Filtration Quality
Disposable filters, with MERV ratings of up to 12, can trap as much as 95% of larger particles. In contrast, washable filters, typically rated between 1 and 4, capture about 75% . This makes disposable filters a better option for homes with allergy or asthma concerns . However, these differences extend beyond air quality, influencing waste management and long-term usage.
Waste Reduction
Washable filters significantly cut down on waste. Over their lifespan, one washable filter can replace 20 to 60 disposable ones . Disposable filters, constructed from materials like fiberglass, cardboard, and metal, are harder to recycle and frequently end up in landfills .
Features Comparison Table
| Feature | Disposable Filters | Washable Filters |
|---|---|---|
| Initial Cost | $15 per unit | $25-75 per unit |
| Annual Cost | $60-90 per year | One-time cost, long lifespan |
| Lifespan | 2-3 months | 5-10 years |
| Filtration Efficiency | Up to 95% | Up to 75% |
| MERV Rating Range | 4-12 | 1-4 |
| Maintenance Needs | Simple replacement | Regular cleaning required |
| Waste Impact | High waste generation | Minimal waste over time |
"It's important to consider that despite the higher initial cost of washable filters, the overall cost will likely level off in the long run"
Conclusion
Here’s a quick recap of the cost analysis to help you weigh the long-term financial impact of your air filter choice.
Cost Breakdown
- Disposable filters: Priced between $10–$50 each, they need replacing every 1–3 months. That adds up to an annual cost of about $60–$90.
- Washable filters: These cost $25–$75 upfront and can last 5–10 years. While the initial price is higher, they save money over time.
For example, ElectroDust offers a premium washable filter priced at $107. It comes with a MERV 7 rating and a lifetime warranty, making it a pricier but durable option.
Choosing the Right Filter
Your decision will depend on your budget and filtration needs:
- On a tight budget? Basic disposable filters ($10–$15) work well for short-term affordability.
- Looking for long-term savings? Washable filters may cost more upfront but can save money over time.
When it comes to performance:
- Disposable filters are better for those with allergies or specific air quality concerns.
- Washable filters (typically MERV 1-4) are fine for general air cleaning.
"You won't need to purchase washable filters very often, so the long-term cost of washable filters will probably be the same or even lower than that of disposable filters."
- Mark Snell, CEO/President, Polestar Plumbing, Heating & Air Conditioning
Before buying, check that your HVAC system supports washable filters and consider the maintenance they require. If convenience is your priority, disposable filters might be the better choice despite their recurring costs.
