Meadow Lake Water Treatment holds a solid rating of 4.6 stars based on 31 reviews. Customers appreciate their competitive pricing and effective treatment solutions. They are often praised for their knowledgeable staff and personalized service. However, with fewer reviews, their reputation is still building, and some may prefer more established options.
Pure Water Northwest has achieved a perfect 5-star rating with 7 reviews, showcasing strong initial customer satisfaction. Users highlight their thorough installations and effective systems. They are ideal for those seeking top-tier water treatment solutions. However, their limited review count means potential customers should consider this when making a choice.
Purified Water holds a rating of 4.4 stars from 45 reviews. Customers appreciate the quality of their products and the straightforward service process. They are a solid option for basic water treatment needs. However, some reviews mention inconsistent customer service experiences, which may be a concern for potential clients seeking reliability.
Filtrific Co LLC has a perfect rating of 5 stars, but it comes from just 1 review. This indicates potential for quality service but lacks the evidence of consistency. The single review praises their products. However, the thin review base makes it difficult to gauge their overall reliability. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is potentially high-quality products. It serves Bellevue, WA, with $50 to $150 pricing, and the honest trade-offs are only 1 review, making it hard to trust.
Cascade Water Alliance has a low rating of 1 star based on a single review. This suggests significant issues with service or product quality. The review indicates poor customer experience, which is a red flag for anyone considering their services. Given the lack of positive feedback, it's advisable to explore other options.
