A UK hobbyist extended HEPA filter life in his DIY air purifier by 40% using custom perforated pre-filters.
Custom Perforated Pre-Filters for DIY Air Purifier Projects: Extending HEPA Filter Life
In mid-2024, a hobbyist in Manchester, UK, improved his DIY air purifier after reading about Sarah Williams’ Texas project (Read Sarah’s case here). His key upgrade? Custom perforated pre-filters designed to trap larger dust and pollen before air reached the main HEPA filter.
Why Custom Perforated Pre-Filters Work
When used in DIY air purifiers, custom perforated pre-filters:
Increase HEPA Lifespan: Captures coarse particles, reducing clogging.
Maintain Strong Airflow: Designed with optimal hole patterns to balance filtration and air volume.
Enhance Unit Durability: Rigid metal panels protect the inner filter layers.
For air filtration design principles, see Environmental Health Perspectives – NIH and Indoor Air – Wiley Online Library.
Case Study: Manchester Hobbyist Build
Before the upgrade, HEPA filters in his DIY purifier required replacement every three months. After installing aluminum perforated pre-filters:
HEPA filter lifespan extended by 40%.
Airflow reduction was less than 5%.
Visible dust on indoor surfaces decreased significantly.

Conclusion
The Manchester project shows that custom perforated pre-filters can significantly extend the lifespan of HEPA filters while maintaining airflow, making them a smart upgrade for any DIY air purifier.
