The 6-month math
Both brands recommend changing the cartridge every ~6 months. Here's what that costs across 2 years.
Purifit, over 2 years
WaterScience, over 2 years
Purifit uses the same KDF WaterScience does
You're not paying more for better chemistry. Both use KDF media to reduce chlorine. Purifit adds two more purpose-built media and skips the premium markup.
KDF
Converts chlorine into harmless chlorides
Activated carbon
Reduces chlorine, smell and impurities
Polyphosphate crystals
Conditions hard water, limits limescale
Neither brand's shower filter reduces TDS. That needs an RO system. Both reduce chlorine and condition hard water so it's gentler on hair and skin.

Not necessarily. Both use KDF media to reduce chlorine. Purifit adds activated carbon and polyphosphate crystals, each with a specific role, without the premium price.
