Are HDX Air Filters Reusable?
HDX air filters are designed for single use and should not be reused or cleaned for reinstallation.
Attempting to wash and reuse an HDX filter will damage the materials and reduce its filtration capability. The filter will no longer form a tight seal in your HVAC system either.
Some key reasons not to reuse HDX air filters:
- Remaining dirt debris will immediately break free into the air.
- Previously captured particles like dust and pollen will also release back into the air.
- Wet filters promote mold and bacteria growth that will spread into indoor air.
- Filtration ratings drastically decrease as materials degrade.
- Reuse leads to faster clogging and poor system airflow.
For optimal filtration, simply replace dirty HDX filters with a fresh one. Reusable options are not recommended.
How Do I Know Which HDX Air Filter Fits My System?
Finding the right HDX air filter for your HVAC system is easy by following these simple steps:

- Test fit the HDX filter before installation to ensure a proper air seal.
With a few quick checks, you can find and install the correctly sized HDX filter for optimal performance.
Do HDX Air Filters Help With Allergies?
Absolutely – HDX air filters can greatly benefit allergy sufferers by reducing airborne allergens in the home.
Higher efficiency HDX filters are designed to specifically trap pollen, mold spores, dust mites, pet dander, and other common allergen particles. This prevents them from circulating through your HVAC system and being spread throughout rooms.
For maximum allergy relief, look for HDX filters rated MERV 11 or higher. MERV stands for Minimum Efficiency Reporting Value, and this rating denotes a filter’s effectiveness at capturing fine particles like pollen and pet dander.
Replacing standard 1″ fiberglass filters with high-MERV HDX filters makes a major difference for allergy symptom reduction and better breathing. Just be sure to change them every 1-2 months during high allergy seasons for best results.
How to Clean an HDX Air Filter?
HDX air filters are disposable and not designed to be cleaned. Any attempts to wash or scrub an HDX filter will damage performance.
The best cleaning approach is to simply replace dirty HDX filters with a new one. This maintains optimum airflow and filtration.
If you need to reuse an HDX filter temporarily in an emergency:
- Gently tap or brush off any loose surface debris outdoors.
- Use a handheld vacuum with a brush attachment to remove deeper dirt.
- Avoid getting the filter wet or using cleaning chemicals.
- Reset the filter to original airflow direction before reinserting.
Keep usage of cleaned filters to an absolute minimum. Replace with a new HDX filter as soon as possible for clean, filtered air.
Are HDX Air Filters Energy Efficient?
Using HDX air filters can improve the energy efficiency of your HVAC system in two ways:
- Lower Resistance – HDX filters have a low resistance to airflow, meaning they make it easier for air to pass through. This reduces strain on your blower motor so it doesn’t have to work as hard.
- Cleaner Equipment – Keeping your air ducts and HVAC components clear of dust buildup improves operational efficiency. HDX filters prevent dirt from accumulating and degrading performance.
Switching from standard fiberglass filters to higher performance HDX filters increases airflow while capturing more particles. Your heating and cooling system won’t have to run longer cycles trying to push air through restrictive filters.
This gives you cleaner air plus energy savings from a more efficient HVAC system. For optimal results, be diligent about replacing HDX filters on schedule.
What is the MERV Rating of HDX Air Filters?
HDX offers air filters across a wide range of MERV ratings from 8 to 16 based on the filtration performance you need:
- MERV 8 – Basic pleated filters for general particle removal.
- MERV 11 – Mid-grade allergen filters for pollen, molds, etc.
- MERV 13 – High efficiency filters that capture fine particles under 10 microns.
- MERV 16 – Specialty medical-grade filtration of nearly all particles.
Higher MERV ratings from 11-16 require more filter material layers and therefore come at a higher price. But the superior HDX air purification is worth the investment for cleaner indoor air quality.
Check your HVAC manual to determine the optimal MERV rating your system can handle. This will provide the best airflow and filtration balance.
Can HDX Air Filters Remove Odors?
Certain higher-end HDX air filters excel at removing household odors and chemical smells using activated carbon filtration.
Carbon has a porous structure that effectively absorbs gases, fumes, smoke, and odors from the air flowing through it. This “carbon scrubbing” effect works to purify the air.
Look for HDX air filters specially labeled for odor removal. These will contain a layer of activated carbon integrated into the filter.
While effective at eliminating odors from the air, activated carbon filters generally have a shorter 3-6 month lifespan. The carbon material saturates over time.
For ongoing odor removal, you’ll need to replace the special HDX odor fighting filters regularly. But this provides noticeably cleaner and fresher indoor air.
How do HDX Air Filters Affect HVAC Performance?
Using HDX air filters has positive effects on your HVAC system performance:
- Increase Airflow – HDX filters have low air resistance, allowing fans and blowers to move more air. This improves circulation and equipment life.
