What Is Whole House Water Filtration?
Whole house water filtration is a complete system designed to treat water as it enters your home. Rather than relying on a single filter, these systems combine multiple treatment stages to address chlorine, hardness, sediment, and dissolved contaminants. Depending on water conditions and usage, a properly designed system may include carbon filtration, water softening, reverse osmosis, and additional treatment technologies.
At Pro Filtration, we design each system based on real water testing, flow rate requirements, and property layout—ensuring consistent performance without pressure loss or unnecessary equipment.

What our customers are saying
Here’s what people think about the Pro-Filtration

Jasmine W.
Great experience working with Sergei and his helper on our new water softener installation. The entire process is smooth – quoting, scheduling, working, and Sergei has been very responsive and communicative. The quote is very competitive and the work quality is great, we got our water softener installed by the end of the construction day, in a good spot in our garage, with some new pipes connecting to the main water valve near the front entrance. Thank you so much. I’d work with Sergei again on future plumbing projects.

Sherry W.
Sergei did a great job installing a water softener in our garage and a reverse osmosis system in our kitchen. I put the job out for bid on Yelp and every other water softener company replied by saying to call them. Sergei gave me a fair price right away and didn’t try to “up” it when he came out like one other guy did. He was always punctual and very neat. He had to cut a hole in the garage wall to get access to the pipes and he covered the hole where it looked nice and neat. He used copper pipes which to me said, “quality.” We had some errands to run so left him alone in our home as we could tell he was a person of integrity. Everything in our home was in perfect order when we got back after he had left. He is trust worthy. Give Sergei a call if you want pure water in your home.

Steven A.
I knew I had found a legit plumber when I spoke to owner Sergei on the phone and got honest, scientific answers to my questions about the best home water systems. Just check out ProFiltration website and you will see their comprehensive approach. Sergei and his assistant installed my Clack salt water softener and carbon filter using copper pipes. It took them less than 4 hours and they cleaned up every step of the way. They also avoided leaving me with open drywall cuts, unlike most plumbers. I’m also very confident that I got a great price on everything.

John C.
Sergei is an honest and competent contractor. He gave us a no nonsense quote that was highly competitive. Good communications throughout the whole process. I watched the entire install and it was done with professionalism and care. The water softener he installed is working well with zero problems. I rarely find a contractor these days who I can enthusiastically recommend to friends and family but Pro Filtration is easy to recommend for value, competence and communications.
Questions And Answers
Is tap water safe for drink?
We can say it is safe to drink in small amounts, though it is not healthy. Municipalities typically add chlorine which in the long run may cause such effects as skin irritations and acne, premature aging, increased risk of asthma or respiratory allergies.
How to remove silica from water?
Removing silica in a commercial or industrial application will depend upon several factors. Though reverse osmosis with permeate flush and proper pretreatment is considered to be the leading technology, as it removes both forms of silica. Contact us for a consultation.
What does hard water mean?
Hard water means that the water contains mineral ions (e.g. calcium, magnesium) which cause dry skin and hair and scale buildup on plumbing appliances.
How long do revers osmosis units last?
They can serve you for 10-15 years with proper and timely servicing and maintenance.
How can I find out my water is hard?
Getting an official report is one of the most accurate and reliable ways to check water composition in your home. We do offer free water test service, don’t hesitate to reach out.
Can I get rid of buildup?
Yes, you can remove the buildup by mixing a bit of vinegar with water. In more complex situations we recommend calling plumbing experts.
