My Buying Guides on Costco Kirkland Vitarain Zero Water
When I first started looking for a reliable water filtration system, I came across the Costco Kirkland Vitarain Zero Water. After using it for a while, I wanted to share my experience and guide you through what to consider before making a purchase.
Why I Chose Costco Kirkland Vitarain Zero Water
I was drawn to this product because of its reputation for delivering pure, great-tasting water. The Zero Water filtration system uses a five-stage filter that removes virtually all dissolved solids, which was a big selling point for me since I’m sensitive to chlorine and other impurities in tap water.
Key Features That Stood Out to Me
- Five-Stage Filtration: I appreciated that the filter goes beyond basic carbon filtration to remove almost everything from my tap water.
- TDS Meter Included: The Total Dissolved Solids (TDS) meter helped me monitor water quality, which gave me peace of mind.
- Large Capacity: The Kirkland pitcher holds a generous amount of water, so I didn’t have to refill it constantly.
- Cost-Effective: Buying this at Costco meant I got a good deal compared to other brands with similar filtration capabilities.
What I Considered Before Buying
- Filter Lifespan: I checked how long each filter lasts. For me, a filter life of about 15-20 gallons was reasonable, but I factored in the cost of replacements.
- Size and Design: I made sure the pitcher fit in my fridge door and was easy to handle. The Kirkland pitcher’s design was compact and user-friendly.
- Water Taste and Quality: I read reviews and tested the water myself. The Zero Water system noticeably improved taste and clarity.
- Maintenance: I wanted something easy to clean and maintain without too much hassle.
My Tips for Using the Kirkland Vitarain Zero Water System
- Always check the TDS meter before and after filtration to know when it’s time to replace the filter.
- Pre-rinse your new filters to remove any loose carbon dust.
- Keep the pitcher refrigerated for the best-tasting water.
- Order replacement filters in bulk from Costco to save money over time.
Final Thoughts
