Just because your water looks clear or smells neutral doesn’t mean it’s contaminant-free. Invisible threats like lead, PFAS, nitrates, and microplastics could be impacting your everyday water supply.
And if there is a hint of fishiness or that pool-like chlorine scent? That’s more than unpleasant; it’s a red flag. All of it adds up to one big question: is your tap water really safe to drink?
The truth is, most of us are sipping water with more baggage than we’d like to admit. And while pitchers or fridge filters might help to some extent, they’re often too little, too late.
That’s where a good under-sink water filter comes in. And if you’re tight on space or sick of bulky countertop setups, the Fortitude Compact is exactly what your kitchen has been missing. Here are five reasons to make the switch. You’ll wonder why you waited this long.
1. It Fits in Small Spaces but Delivers Powerful Results
Let’s be honest: most of us don’t have room for a water station that takes over the entire kitchen. The Fortitude Compact under-sink water filter system is made for small homes, tiny apartments, and anyone tired of counter clutter.
It installs cleanly under your sink, no drama or drywall, and gets to work immediately. If you're searching for the best water filter for apartment life or something easy to tuck away, this one's your winner. It’s also easy to install an under-sink water filter. You don’t need a plumber or a full weekend to get it going.
2. You'll Actually Want to Drink Water
Filtered water that tastes good? Under-sink systems are a total game changer. They're a simple solution so your water tastes clean, crisp, and refreshingly drinkable.
Aquasure Fortitude Compact
And if you’ve been wondering how to remove chlorine from tap water, Aquasure's Fortitude Compact handles it with ease. The carbon filter tackles chlorine, bad tastes, and chemical byproducts. Meanwhile, the KDF media in the water filter helps reduce heavy metals and microbial buildup.
The result? Tap water that doesn’t taste like a swimming pool. Just clean water you’ll actually want to sip, cook with, and pour for your family.
Aquasure Premier Series Advanced Water Filter
If you’re looking for the gold standard in purity and taste, under-sink reverse osmosis water filters take things even further. Reverse osmosis (RO) removes up to 99% of contaminants. And Aquasure’s Premier Advanced Series Reverse Osmosis Water Filtration System even adds minerals back with an alkaline remineralizing filter.
It’s clean water with a fresh, mineral-rich taste that’s perfect for hydration. It’s also the perfect base for smoothies, tea, or your morning coffee. (And yes, filtering water for coffee really does make a difference.)
Pro Tip: We love adding electrolyte powders like LMNT, Nuun, and Liquid I.V. to our reverse osmosis filtered water. Or, if you want to truly optimize your health and hydration, Athletic Greens is a full spectrum supplement that tastes great with RO water.
3. It Filters Out More Than You Think
Don’t let the small size fool you. The Fortitude Compact doesn’t just mask bad taste. It tackles the stuff that shouldn’t be in your water to begin with.
Its carbon filter and KDF media combo pulls double duty. Wondering what does a carbon filter remove from water? Think chlorine, VOCs, pesticides, and bad tastes. KDF steps in to help with lead, mercury, and microbial growth in the filter housing.
In short: this isn’t surface-level stuff. It’s real protection from real contaminants. And if you're ready to take it even further, it pairs beautifully with an under-sink reverse osmosis water filter for an extra layer of purity.
4. Say Goodbye to Pitchers and Plastic Bottles
We all start out with good intentions: buy the pitcher, wait for it to filter, forget to refill it, get annoyed. Or worse, you forget when you last changed the filter and fall back to grabbing bottled water at the store... Again.
But if you’re comparing an under-sink water filter vs pitcher, the comparison is a no brainer. An under-sink filtration system gives you filtered water without the hassle, waiting, or plastic waste. It cuts down on single-use bottles and filters better than most pitchers ever could.
Plus, with Aquasure’s Subscribe and Save, you can get replacement filters for your system delivered to your door so you never forget to reorder. And,enjoy a discount with each filter replacement.
5. More Than Just Drinking Water
Sure, an under-sink water filter gives you great-tasting water straight from the tap, but its real power goes way beyond your glass.
Filtered water isn’t just for hydration. It’s the foundation for better meals, cleaner coffee, and everyday essentials you don’t even think about. Whether you're rinsing produce, boiling pasta, or filling your pet’s bowl, filtered water for cooking makes a difference you can taste.
An under-sink system doesn’t just purify your water. It improves your whole routine. One simple system, quietly powering everything from family dinners to solo tea time.
