Only DVS can offer BioShield Healthy Infusion treatment of your filters.

BioShield 75 is a patented revolutionary new product that prevents the growth of a wide array of bacteria, mould, mildew, algae and yeast.  It protects against odour-causing microbes, microbial deterioration and discolouration. Its properties provide safe protection when applied to filters and to working surfaces in the home and workplace.

BioShield 75 is EPA Registered and USDA accepted and has now been accepted by New Zealand authorities. It is a non-leaching, non-toxic treatment approved for use in the home and with air filters.

BioShield 75 acts like a bed of microscopic spikes that pierce the cell walls or microbes. It is a totally new approach to providing long lasting antimicrobial protection.

DVS is able to treat its filters with BioShield and this application will be effective as long as the filter material remains free of dust build-up to the extent that air passing through the filter can come into contact with the surface of BioShield-treated filter material.

This means that the benefits of BioShield treatment of DVS filters will match the normal period between filter replacements.

BioShield is extensively used in the USA by restaurants, caterers, food processors, as well as the hygiene, hospitality, travel and health industries. It has been adopted by NAPA to treat its cabin air filters.

BioShield is new to New Zealand. Besides DVS, several leading manufacturers have adopted BioShield for the treatment of furnishings, carpet and paint products.

BioShield treatment of home ventilation filters is exclusive to DVS and is an example of the DVS commitment to helping create a healthy, comfortable home environment for its customers.
