I have found that the water filter replacements required a lot of force to install, and I even broke the housing where the filter mouth engages. I used a store-bought whirlpool/pur/kitchenaid filter cartridge. Are there variances on the filter locking collar and perhaps there is a better fitting filter?
ANSWER Hello Daniel. No, they are very tight to prevent the unit from leaking.
