Drain Guard (DG) was invented in 2003, the SARS year in HK, and was granted the Champion Award in the Original Household Product Design Competition. DG is the first product in HK (may be the first in the world) that was designed for protecting the indoor drain gates from outside harmful substances. The design concept was inspired by the case in the Amoy Gardens that the virus was spread through the whole building through the drain pipes. That means many common virus nowadays such as H5N1, H1N1, H3N2 can enter the apartments in the same way. Therefore it was urgently to have a product invented to solve this problem. That is why DG was born, and it has the following features:
- Block sewage odors and harmful insects
- Block hazardous gas or vapors that may contain virus or bacteria
- Work like ordinary drain gates that allows normal water drainage
- The exposed OWE (One-Way-Exit) door design allows easy visual inspection
- Totally DIY. No need of any technician
- Various surface finishing designs for different interior designs.
Since 2003, many families in HK have been using DG in their apartments. Word of mouth proves that DG are effective products. Now much improvement and upgrades have been built into the second generation DG. Expecting that even more users will be willing to use DG in future.
- 專利外露式活門設計, 運作是否正常可一目了然
為了照顧小數的不標準渠閘用家, 新開發產品還有專為 DG1 和 DG2 而設計的轉接片和髮隔，使到它們的用途更為廣泛。
