Did not come with male quick-connect adapter to plug into the water faucet. Appears to be impossible to install without the same male connector part (already on one side of each hose) installed on both sides of the output hose (this needs to be on both sides of the output hose, or at least come as an attachable adapter to be screwed onto the output hose). If it had this male quick-connect part, it could be installed by simply inserting that connector part into the quick-connect receiver on the water faucet, but without it, it seems like a useless filter since there are no separately sold male quick connection adapter parts readily for sale anywhere. I'm shocked how difficult/impossible this water filter is to install at home given how expensive it is and that it seemed to be marketed for at-home use. Maybe it is only for specialized industrial applications, and not for at-home use. Below is a link to the water faucet I am trying to connect it to. This faucet worked great with the Filtrete filter system. So far I am highly recommending Filtrete over Waterdrop given its easy non-technical installation and lower price for excellent quality filtered water. https://www.amazon.com/Drinking-Stainless-Kitchen-filtration-Lead-Free/dp/B076FRXVKY?pd_rd_w=GlnIy&pf_rd_p=ed61186e-0a73-4f70-9288-c08a29fffa70&pf_rd_r=9TSH1F79C92K6QT4PH7R&pd_rd_r=3d2fd59f-5b31-4e1a-95b9-98c224c2d462&pd_rd_wg=OYnaN&pd_rd_i=B076FRXVKY&psc=1&ref_=pd_bap_d_rp_15_i Here is the easier to install Filtrete filter system I mentioned: https://www.amazon.com/Filtrete-Maximum-Filtration-Reduces-3US-MAX-F01/dp/B01L0ADGUO?pd_rd_w=MEV7X&pf_rd_p=ed61186e-0a73-4f70-9288-c08a29fffa70&pf_rd_r=BDK8NKSXGBQ3DJSJ82ES&pd_rd_r=9773d088-919e-4284-99df-3996b96cb91e&pd_rd_wg=rD3o2&pd_rd_i=B01L0ADGUO&psc=1&ref_=pd_bap_d_rp_3_i
