Advice Needed: under-Sink Water Filtration System for PFAS Removal

I'm planning to install an under-sink water filtration system in my kitchen.

My main priority is removing PFOS and PFOA (types of PFAS) from our drinking water. Recent news about these contaminants in Australian tap water has us concerned.

Secondary goals include removing contaminants from old building pipes and improving water taste.

I'll be doing the installation myself, so I'm leaning towards a simpler inline filter setup rather than reverse osmosis. I'm considering single, dual, or triple filter configurations.

Questions:

  1. What filter brands have you had good experiences with?
  2. Should I stick with my current kitchen faucet or upgrade to one with a separate filtered water outlet?
  3. Is a single, dual, or triple filter system most appropriate for my needs?
  4. What's the most cost-effective approach?

Any advice on achieving effective PFAS removal while balancing ease of installation and maintenance would be greatly appreciated.

Thanks!

    I would recommend the Merck Millipore water filtration system. Makes water as pure as possible.

      Not looking to get into an argument but I don't think Milli-Q water is suited for long term human consumption. For science it's great.

      Basically, when you drink that water, it takes minerals from you.

    I havent checked if there is a cheaper listing. But this is one I bought and had installed in Feb this year. Since we were renovating the kitchen I had the plumber install as they were here. Otherwise I would have done it myself. It comes with spare set of filters.

    So far happy with its performance and changing filters appears easy

    Have a good range. Also have conversion kits if you have puratap

    I have a Waters Co 10L benchtop filter. It's not an under sink connected thing, it's separate and you fill it up yourself.

    The filters they provide with the purchase last 5 years. Replace the cotton pad every 2-3 weeks, clean the jug every 3 months and replace the first filter every 10 months. There's more details on what it filters out on the site.

    Can you provide more info on the concerns about tap water? Want to learn more

      Go warch movie 'Dark Waters'. Based on true events.

      I knew from my mum that (for example) non-stick was bad, but that movie sparked me to look more into it.

      Apparently USA have controls that have limits of 4 nanograms ler liter PFOA where Australia has 70 nanograms.

        If it's that bad we would all be dropping like flies. Nearly everyone consumes tap water and cooks on non stick pans.

          Ya i still drink straight from the tap and have done since forever.

          Sorry, with my original comment, the concern for cooking with non-stick, as raised to me, was when it was scratched, flaking, conpromised etc.

          Well (some people are dropping like flies)[https://www.theage.com.au/national/victoria/cancer-cluster-led-to-16-deaths-at-fiskville-cfa-training-centre-study-finds-20150121-12ur7b.html]. However they obviously have significantly higher levels of exposure than the rest of us. But it accumulates in the body and most people aren't really aware of their exposure.

          Much like there are pack a day smokers who live for decades, or that a couple of generations are probably stupider because of lead in fuel, how bad something is isn't always measured in short time frames. Governments are taking this extremely seriously for good reason.

    Where are PFAS found?

    Cleaning products.
Water-resistant fabrics, such as rain jackets, umbrellas and tents.
Grease-resistant paper.
Nonstick cookware.
Personal care products, like shampoo, dental floss, nail polish, and eye makeup.
Stain-resistant coatings used on carpets, upholstery, and other fabrics.

    Do your research thoroughly, from what I read there are only a few filtration systems types that remove PFAs.

    i just installed a 3-ways tap - hot/cold & filter water - last week in my kitchen.

    the ebay seller i bought mine off a month ago no longer stocks them

    but a black version can be bought here for $64 delivered using code TJULY15

    I had the same tap in my old house - which I used for 5 years (sold house) with a 2 stage water filter with no issues.

    I'll install a 2 stage filter in my current kitchen shortly.

    I'll buy something like this

    2 stage 10" water filter system, Say the town water has a TDS of 200 after it goes through a 2 stage the TDS will still be 200 TDS.
    R.O reverse osmosis filter system will take the TDS down to around 3, and then it still doesn't remove everything.

    There is a shop in the USA that sell filtration system for aquarium owners, they do a lot of "how too's" on YouTube. These guys might have thousands of dollars worth of fish in their tank, so they can't afford to make any mistakes with their water, and do a lot with RO systems setup videos.

    This will give you an idea of what things do. https://www.youtube.com/watch?v=58J4Jrw4ZbY&ab_channel=BRStv…

    What levels of PFOS and PFOA are currently in your water?
