The problem with HEPA and why SecureAire is better

HEPA filters have been a staple in air purification since 1942. Lessons from COVID-19 remind us that the smallest particles and pathogens often remain suspended indefinitely. HEPA cannot filter these and other toxins that remain suspended and never get to the filter media. The latest research proves that SecureAire is better than HEPA – because we should measure particles within our breathing space, not just at the filter.

HEPA filters don’t capture the smallest and most dangerous airborne particles

The makers of HEPA filters claim their filters remove nearly 100% of harmful airborne particles. But this is misleading! HEPA filters only remove the particles and pathogens that reach the filter. The smallest and the most dangerous particles never get there. HEPA filters rely only on airflow – which can’t move some of the smallest and most dangerous particles. Tiny “ultrafine” particles – including COVID – are too small to be moved by the air and never reach the filter. Instead, they remain suspended in your breathing zone.

HEPA filters don’t kill or inactive viruses

HEPA filters are often made of thin fibers that don’t kill viruses or bacteria. Some particles may reach the filter and are trapped, but they are not killed or inactivated. Instead, HEPA filters can become breeding grounds for MOLD.

HEPA filters have no published human studies on infectious clinical outcomes

Because HEPA filters are so common, many people assume that there is scientific evidence to prove just how effective they are. However, there are no real-world, long-term infection control studies proving that HEPA is the most effective filter for cleaning indoor air.

SecureAire’s real-world-tested technology is the better option

SecureAire’s technology is 95% more effective at removing tiny “ultrafine” particles than HEPA filters alone, according to a comparative study conducted by scientists.

The bottom line: don’t be fooled by marketing claims – Examine the science and get the air purification system that is 95% better than HEPA.
