Build your ideal multi-zone HVAC system with MRCOOL’s latest 5th Generation Wall-Mounted Air Handlers. These sleek, ENERGY STAR® Certified indoor units are specifically designed for compatibility with the 5th Gen MRCOOL Multi-Zone DIY outdoor condensers and Quick Connect line sets using R-454B refrigerant.

Perfect for homeowners who want professional performance with DIY simplicity, each unit offers ultra-quiet operation, modern styling, and unmatched energy efficiency—backed by one of the easiest installation processes in the industry.

Product Highlights:

  • ENERGY STAR® Certified for maximum energy savings and efficiency
  • True DIY Installation – no special tools or HVAC license required
  • Available in 9k, 12k, 18k, 24k, and 36k BTU capacities to match any room size
  • Includes 25 ft. control wire (used with matching 25 ft. line set)
  • Quick Connect compatible with MRCOOL pre-charged R-454B line sets (sold separately)

📋 Installation Note:

Every wall-mounted air handler comes with a 25-foot control wire included in the box. If your installation uses a longer line set (35, 50, or 75 feet), you will need to swap out the included 25 ft wire for the longer control wire that comes with your selected line set. This ensures reliable communication between the indoor and outdoor units without voltage drop or wiring issues.

Each air handler requires a dedicated line set and control wire. Make sure your selected components match the distance from the air handler to the condenser for best results.

⚠️ Note: This listing is for indoor wall-mounted air handlers only. Please pair with a compatible 5th Gen MRCOOL Multi-Zone outdoor condenser and DIY line sets to complete your system.

Tastes great, works great
I love this toothpaste! I’m so happy to have a toothpaste that isn’t mint-flavored. FLAVOR: The taste and smell are so good — the coco ginger flavor is delicious and I legitimately look forward to the taste of it. I was worried that the ginger might be strong/spicy, but it’s nicely balanced. The lavender lemon flavor is also pretty good, like a lemon pastry. The elamint flavor tastes like regular mint toothpaste, just maybe slightly more herbal. SENSITIVITY: I’ve had to use sensitive toothpaste for many years. Any time I switched off it, I would start experiencing sensitivity again within a week or so. I’m really happy to report that this toothpaste offers great sensitivity and enamel protection. WHITENING: I don’t feel that this toothpaste is contributing much in terms of whitening. My previous toothpaste had gentle whitening, and I do feel like I could tell it was working. While my teeth haven’t gotten less white since I switched to Boka, I don’t think they’ve gotten any whiter either. That’s okay with me — the flavor and sensitivity protection are worth it, and I can always do a whitening treatment in the future if I ever feel I need to. TEXTURE: The texture is just like normal toothpaste and brushing with it feels the same as any other toothpaste. It works great with both my manual toothbrush and my electric toothbrush. TUBE: The tube is really nice and sturdy. I like the design of the tube a lot. The text and color scheme are fairly minimalist, and I like that the cap has a wide base so the tube can stand upright. It looks nice on my bathroom shelf. My only small complaint is that it gets harder and harder to squeeze the toothpaste out once the tube is less than half full. Since the tube is so sturdy, it can’t be rolled and folded to get the paste out. I think this issue could probably be resolved easily with one of those squeezing tools, though. I’ll report back if I try it. SIZES: I love that it’s available in both a regular size and a little travel size. I also loved that the travel size allowed me to try out this toothpaste before committing to a whole large one. (Don’t worry, the tube in my photos was full when it arrived! I’ve used half of it.) Overall I highly recommend this toothpaste! I will absolutely buy it again.

Taste Great
This is a great tasting all natural toothpaste that actually does what it claims. My teeth feel so clean and fresh after brushing and the whitening is immediately noticeable, something that caught me by surprise. It's super easy to use and functional like any other toothpaste but without all the foaming at mouth. The ingredients are natural and it's fluoride free. I was looking for more of the ginger to come through but sadly it's hardly noticeable. I do like it but will try the other flavors next time.

Favorite toothpaste! Love the Ginger Flavor
This is my favorite toothpaste! I have very sensitive teeth and this has improved that sensitivity quite a bit. I like that Boka offers many different flavors that aren't typical "kid flavors." I know some folks, especially neurodiverse, are averse to mint and the ginger is nice and refreshing without being overpowering. Nano toothpaste is easy to use, doesn't require water even, and is a nice consistency like a gel. No gritty feeling like with typical toothpaste. My dentist was please with my teeth last time I visited after using for 6 months, so it's doing what it's supposed to do.

Good toothpaste, some flavors not so good
Cleans fine but I really do not like the cocoa ginger flavor. Lemon lavender is really good.
