July Air Filter Check: Protect Your Home and HVAC System This Summer

With longer days and hotter temperatures, July is when your air conditioner works the hardest. But what many homeowners forget is that a dirty or undersized air filter can quietly rob your system of performance, drive up energy bills, and shorten the life of your equipment.

Here’s why July is the perfect time to check your filter—and how to make sure you’re using the right one.

Why Summer Puts Extra Strain on Your Filter

When your HVAC system runs more frequently in July, it pulls more air—and more contaminants—through the filter. Dust, pet dander, pollen, and even wildfire smoke in some areas can build up quickly, especially in high-MERV filters or smaller 1-inch pleated designs.

If you haven’t changed your filter in the last 30–90 days, it’s likely restricting airflow and making your AC work harder than it should.

Pro Tip: If your system sounds louder than usual or rooms feel stuffy, your filter might be overdue for a change.

How to Choose the Right Filter for July

Not all filters are created equal. Here's how to pick the right one this season:

• MERV 8–10: Great for everyday homes. Balances airflow and dust control.
• MERV 13: Ideal for allergy season or wildfire smoke. Captures finer particles like pollen, bacteria, and smoke.
• Fiberglass (MERV 1–4): OK for basic protection, but not for filtering allergens or fine dust.
• Custom Sizes: If your filter doesn’t fit snugly, you’re losing efficiency. We make Exact Filters® to your dimensions down to 1/8".

Signs You May Need a New Filter Now

• You can't remember the last time it was changed
• The filter looks gray or packed with dust
• There's increased dust around your vents or home
• You’ve had higher energy bills lately
• You or someone in the home has worsened allergies
