Which water filter should I buy? There are so many options out there, I'm totally confused.
You are informed about good water and have recognized that pure water is an indispensable elixir of life for healthy metabolic processes and that pure, living water is one of the most important prerequisites for a long, disease-free life. You don't want to drink any drug residues, hormones, or microplastics in your water, for which there are no limits and therefore no regulatory authority. You don't want pesticides, fertilizer residues, asbestos fibers, heavy metals, or anything else in your tap water, even if these substances are "only" below the limits in your drinking water.
You just want pure, good drinking water!
You've decided that you need your own mountain spring at home and want to reap the many financial and health benefits that come with it. Now you are looking for the best water filter for you, but the huge selection is overwhelming and you don't know which water filter you should treat yourself to?
You're not alone. I'm a member of a Telegram group called Water Filters, and this exact question comes up all the time.
Since we at wasserfilter-berlin.de have gained almost 20 years of expert experience in this field, we can help you. Below, I'll introduce you to three water filters, one of which is guaranteed to be the right one for you, producing wonderful, comforting, soft water:
1.) Pi Power Compact Standard for 2,350 euros. 
For you, only the best is good enough. You don't have to worry about a budget. You want to transform your tap water into the finest high-mountain spring water. Here's your system:
In my opinion, this is the best water filter system currently available on the water filter market. Very solid technology without unnecessary frills, and truly delicious, vital water. You can request a free sample from us. Click here and read the details. By the way, there are several versions available, including ones with even higher flow rates. But this one is by far the most popular. With this system, you have your own mountain spring right in your kitchen.
800 GPD Direct Reverse Osmosis Flow System for 799 Euro 
If your budget doesn't (yet) allow for the PI Power Compact, this is the second-best option. It requires a bit more space, doesn't offer as much flow, and isn't as elegant as the PI. It doesn't offer comprehensive revitalization, but the result is water free of all contaminants and limescale. You can retrofit a small revitalization system, but you won't achieve the revitalization values of the Pi system. Click here to read the details.
Small Reverse Osmosis 100 GPD for 69.90 Euro 
You don't have any money to spare, but still want to start filtering your tap water now. Then this water filter is for you. This system requires patience. It takes about 30 minutes to make a glass of water. However, this water will be almost as pure as with the 800 GPD (option 2). You just have to plan, filter in advance, and keep filled carafes in the refrigerator. Many people start this way and then upgrade later.
My conclusion: If at all possible, invest in a PI system. You'll probably end up there later anyway. Consider how much money you'd put into a car. This is about your body, your health. Is a car more valuable to you than your own body? Perhaps you already have health problems due to a poor diet and poorly hydrated water, or you have excess fat on your hips. This is where good water can help you get healthy and reach your ideal weight faster. Check out the testimonials from others: Link
I wish you a good decision!
