AstroCel HEPA Filters by AAF Flanders: A Buyer's Guide
When an application demands the very highest level of contamination control, standard pleated filters simply aren't enough. AstroCel I High Efficiency Particulate Air (HEPA) filters by AAF Flanders are engineered for exactly these environments, capturing at least 99.97% of airborne particles at 0.3 microns. As an authorized AAF Flanders retailer, Remember the Filter supplies AstroCel HEPA filters built and tested to your specifications.
What makes a HEPA filter different
HEPA is a performance standard, not a brand. To qualify, a filter must remove at least 99.97% of particles at the most-penetrating particle size of 0.3 microns, an efficiency far beyond even the highest MERV-rated commercial filters. AstroCel I filters meet that standard and are individually tested for certified performance, so each unit ships with documented proof it performs as rated. If you're weighing HEPA for a residence rather than a critical facility, our guides on whether HEPA is right for your home and how much HEPA cuts down on dust are the right place to start.
Where AstroCel HEPA filters are used
AstroCel I filters are built for spaces where contamination control is mission-critical:
- Semiconductor and electronics manufacturing
- Pharmaceutical processing
- Photographic film manufacturing and processing
- Hospitals and healthcare facilities
- Universities and research laboratories
- Food processing
- Asbestos abatement
These are the same cleanroom and critical-environment settings where filtration is a regulated part of the process, not just a comfort measure.
Configuration and performance options
Part of what makes AstroCel I versatile is how many ways it can be built. Twelve separate criteria, spanning materials and performance, go into each filter, so careful selection produces a unit tuned to your exact application. Available options include:
- A wide range of standard sizes, plus special sizes fabricated to order
- Multiple cell-side constructions and efficiency levels
- High-temperature models rated up to 750°F
- A high-capacity option for higher airflow, up to 500 FPM
- Gasket or gel-seal options for a leak-free installation
- Optional UL 900 or UL 586 labeling
Because HEPA filters are the final and most sensitive stage of a system, they perform best when protected by upstream filtration. Pairing them with quality pre-filters extends their service life and lowers cost, our guide to commercial HVAC pre-filters explains how that staged approach works, and our overview of air filtration housings covers the equipment that holds it all. For processes that run hot, see our article on high-temperature air filtration.

How to order AstroCel HEPA filters
Because AstroCel I filters are configured to your specific application and individually tested, they are quoted rather than sold off the shelf. Lead times typically run 4 to 8 weeks to allow for production and certification testing. Reach out to our filtration specialists with your size, efficiency, temperature, seal, and labeling requirements, and we'll prepare an accurate quote. If your project also needs standard commercial filtration, you can browse our full range of HVAC filters and custom-size filters in the meantime.
Frequently asked questions
What does 99.97% at 0.3 microns actually mean?
It's the HEPA standard. The filter removes at least 99.97% of particles at 0.3 microns, which is the hardest particle size to capture. Larger and smaller particles are captured at even higher rates, making HEPA the benchmark for critical contamination control.
Can I install an AstroCel HEPA filter in my home HVAC system?
Usually not without modification. True HEPA filters create high airflow resistance that most residential blowers aren't designed to overcome. For homes, a high-MERV pleated filter is typically the better balance, our HEPA-for-homes guide explains the tradeoffs.
How long does it take to get AstroCel filters?
Because each filter is configured to your specification and individually tested, plan on roughly 4 to 8 weeks for production and certification. Submit your requirements to our specialists for an accurate quote and current lead time.
