The fundamental difference is that TPA® actively destroys bio-contaminants through a high-voltage electrostatic field, whereas HEPA filters only passively trap particles on a mesh screen.

 

TPA® captures particles as small as 0.0146 microns—substantially smaller than the 0.3-micron limit of standard HEPA filters. Additionally, TPA® deactivates viruses and bacteria rather than allowing them to accumulate live on a filter surface.

Yes, TPA® technology is significantly more cost-effective over a 3-to-5-year commercial lifespan because it eliminates recurring HEPA filter replacement costs and reduces maintenance downtime.

 While traditional HEPA systems require replacing costly filter elements every 3 to 12 months (costing $100–$500+ per unit annually in commercial setups), Airdog TPA® collector plates are 100% washable and reusable, bringing consumable costs down to zero.
