The Implosion Proof Collection Canister is self-contained. Every port is sealable and has built-in caps. Either end of the contaminated suction hose is easily sealed just by pressing the ends on the ports. The high-flow pathogen filter that is housed in the lid separates out dangerous airborne bacteria. This device has a clinically proven 99.99% DOP rate. It is easy to see aspiration, which is different than liner bag bottles. This canister is also extremely simple to clean, and prevents plumbing from getting clogged. This device has 10 years of being implosion proof.
