Its 5/16-inch thick foam pad uses activated charcoal, making it highly efficient at capturing large particles including dust, pet hair, lint, and smoke. This thickness offers superior filtration compared to ultra-thin options. The filter is washable and reusable, extending its lifespan and reducing waste. It is an effective solution for protecting your main filter from clogging and maintaining air cleanliness in your home environment.

It effectively traps dust, pollen, pet dander, and other pollutants, boosting indoor air quality. Measuring 24" x 15" x 1/4", it fits most window air conditioners and can be cut smaller if needed. The material choice reduces filter fragility and increases durability, making it a cost-effective way to keep your unit cleaner while ensuring fresher air in your living space.

Featuring compatibility with various part numbers (such as AP4538886 and AH2577777), it is intended for particular AC models and may not be cut to fit other units. Its white filter screen design makes it a simple, direct replacement for worn-out or missing filters.

Buying Guide: What to Consider When Choosing Cheap Air Conditioner Filters
Choosing the right air conditioner filter involves more than just picking the cheapest option. Consider the following factors to ensure you get the best value and performance:
Filter Material
- Foam Filters: Common and affordable, foam pads are washable and reusable. They effectively trap large particles but may have limited capacity for finer dust.
- Electrostatic Polyester: These offer better filtration than foam and are more durable, capturing smaller particles like pollen and dander effectively.
- Filter Screens: Usually specific to certain models, these can block bigger debris but may not filter microscopic particles.
Size and Fit
- Cut-to-Fit: Flexibility in size can save money by accommodating various AC models. Filters that can be trimmed to exact dimensions help prevent air bypass and maintain system efficiency.
- Precise Size: Some filters come in fixed sizes tailored for particular AC units, ensuring perfect fit and ease of replacement.
Filtration Efficiency
- Thickness: Thicker filters generally capture more particles but may slightly restrict airflow. Find a balanced thickness for your specific unit.
- MERV Ratings: Some household filters list MERV ratings indicating filtration efficiency. While cheap filters might not show this, higher ratings mean better particle removal.
Maintenance and Longevity
- Washable Filters: Reusable foam or polyester types can be cleaned to extend use, reducing waste and ongoing costs.
- Replacement Frequency: Replace filters regularly (every 30 to 90 days depending on usage) to maintain air quality and AC performance.
Compatibility
- Always verify the filter dimensions and compatibility with your AC brand and model before purchase. Using incompatible filters can lead to leaks, poor air quality, or mechanical issues.
