If you’re a homeowner in Redmond, Oregon, you likely know how crucial heating and cooling systems are for year-round comfort. But one simple maintenance task is often overlooked—changing your air filters. It might seem like a minor detail, but a dirty filter can dramatically impact your indoor air quality, HVAC performance, and even your health.
In this article, we’ll answer how often you should replace your air filters in Redmond, what factors affect this frequency, and why it matters more than you think.

🌀 Why Air Filters Matter for Redmond Homes
Air filters trap airborne particles like dust, pollen, pet dander, mold spores, and even bacteria before they circulate through your HVAC system. Redmond’s dry summers and pollen-heavy springs make air filtration especially important. A clean filter ensures your HVAC system isn’t overworking to move air—saving energy and prolonging equipment life.
According to the Mayo Clinic, clean indoor air plays a significant role in managing allergies and respiratory issues. If anyone in your household suffers from asthma or seasonal allergies, frequent filter changes are non-negotiable.
📅 How Often Should You Replace Air Filters in Redmond?
Here’s a general rule of thumb:
| Home Type | Filter Change Frequency |
|---|---|
| No pets or allergies | Every 90 days |
| One pet | Every 60 days |
| Multiple pets | Every 30–45 days |
| Allergies/asthma | Every 20–45 days |
| Vacation home | Every 6 months (if rarely used) |
However, this varies based on local conditions and lifestyle factors.
🌲 Factors That Affect Air Filter Lifespan in Redmond
1. Outdoor Air Quality
Redmond experiences occasional wildfire smoke and dusty winds in late summer. During these events, filters clog much faster. If you smell smoke indoors or see haze outside, check your filters weekly.
2. HVAC System Usage
If your system runs year-round—for heating in winter and cooling in summer—you’ll need to replace filters more frequently than if you only use it seasonally.
3. Home Size and Occupancy
Larger households create more indoor pollutants through cooking, laundry, and general activity. More people = more frequent filter changes.
4. Pets
Pet hair and dander are common reasons for clogged filters in homes. If you have dogs or cats, consider changing filters monthly.
🚩 Signs It’s Time to Replace Your Air Filter
Not sure when it’s time for a change? Watch for these signs:
- 🔥 Reduced airflow from vents
- 🤧 Increased allergy symptoms
- 💨 Dust buildup near vents or returns
- 💡 Higher energy bills
- 📦 Filter appears gray or clogged
To stay ahead, set a reminder on your phone or add it to your monthly maintenance checklist.
🛠️ What Type of Filter Should You Use?
The MERV rating (Minimum Efficiency Reporting Value) tells you how effective a filter is at trapping particles:
- MERV 6–8: Basic residential filters, replaced every 60–90 days.
- MERV 9–12: Better for allergies and homes with pets.
- MERV 13+: Hospital-grade filters—not always compatible with standard systems.
