The cassette works with the MrCool® DIY® Quick Connect® line set and the No-Vac® Coupler to increase the length of the line set. Not only does the unit offer quiet operation and multiple operating modes, but it also features the Elevation function that lowers the filter panel for easy air filter maintenance. Purchases of the MrCool® DIY® Series 6K and 9K BTU Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 4 Zone Ductless Mini Split System - 6K + 6K + 9K + 9K can cool through the Summer, heat through the Winter, and dehumidify through the wet seasons. Plus, you can quickly check the temperature of each room in your home from the easy to read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The four MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

The MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 Four-Zone Ductless Mini Split Air Conditioner System - 6K + 6K + 9K + 9K comes with many options, so you can customize your system based on your needs. Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Easily maintain your MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 Four-Zone Ductless Mini Split Air Conditioner Unit with alerts and reminders. Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes. Air filter cleaning alerts are automatic, and you can easily keep the minimal indoor units clean with a dry or damp cloth.

LONG DESCRIPTION
The brand new 5th Generation MRCOOL® DIY® 36k BTU Multi-Zone Ductless Mini-Split Condenser is the right choice if you need immediate, effective comfort that won’t break the bank! This system, which can be installed without the assistance of an HVAC professional, is one of the most efficient and innovative HVAC options on the market. With this condenser, you’ll be able to heat and cool up to 5 different spaces equaling around 1,500 square feet, meaning you can potentially heat and cool an entire home with just one mini-split system! Our DIY® Mini-Splits are able to forgo the evacuation and charging process because our patented Quick Connect® line sets are pre-charged with R-454B refrigerant, a more efficient and eco-friendly refrigerant than R-410A, which we have previously used. These line sets are sold separately. This unit achieves a SEER2 of 23 and an HSPF2-4 of 9.9. These fittings make installation an incredibly safe and simple process, allowing you to save a lot of time and money. There are a variety of features to explore once the system is up and running. One of them is the ability to integrate your system with the SmartHVAC app, allowing you to control your comfort with the touch of a button. You can even go a step further and link your Amazon Alexa or Google home for touchless operation. With the app, you can set each zone’s temperature, set schedules for each unit, monitor your system’s energy usage, and more. There are even more features to explore that will help you customize your comfort to be exactly what you want. We’ve got your back in the unlikely event that your system malfunctions. Your system will come with a 5 year parts warranty and a 7 year compressor warranty, and if you enroll in the MRCOOL® Care Program, you’ll be able to enjoy the Limited Lifetime Replacement warranty! For the best comfort you’ve ever felt and a sense of accomplishment as icing on the cake, choose the MRCOOL® DIY®!

Good Product
Size: 60 Count (Pack of 1)
These cotton swabs are very soft and gentle. They feel sturdy and do not fall apart easily, which I appreciate. The baby-safe tips make them more comfortable to use, and the organic cotton is a nice plus. Good quality and useful to keep on hand.

The Best for Baby! A New Parent Must-Have!
Size: 60 Count (Pack of 1), Size: 60 Count (Pack of 1)
After you make your baby registry, you think that you've considered everything you need and are prepared for just about anything - but oftentimes we forget the little things that we will use on a regular basis and these cotton swabs are one of those things that never crossed my mind until push came to shove... I absolutely love the "baby cotton swabs. The way the q-tip is made is fantastic as it does not allow you to go too far into the babies ear canal. It has a thinner tip for ear cleaning which meets a thicker "fluffier" cotton base. My daughter moves around a lot, so being extremely careful unfortunately is simply not enough once she started becoming more mobile. She will move her head or jerk around and this safety feature does not allow me to accidentally insert too far in. Additionally, it cleans the ear very well, the skinnier tip is great for wax build-up inside the canal while the larger thicker part is also fantastic for cleaning/drying ears outside of the ear canal/around the ear opening. I use these for clearing out baby's ear wax, drying the outer ear canals after bath, I've even used them after she got her ears pierced to ensure no saline solution has gotten inside of the canal. I went to the pediatrician and received a compliment about how clean her ears are and she mentioned she sees a lot of parents struggle to keep their babies ear clean. She asked what we were doing and I let her know about these and she let me know she would start recommending it to parents. I will continue using these until my daughter is old enough to clean her own ears, this is my 3rd box and I like them so much I've even added them to my subscribe and save.

Pure and Simple — My Go-To Organic Cotton Swabs
Size: 500 Count (Pack of 1)
These Sky Organics cotton swabs are my new favorite. I use them after my shower, and they feel soft but sturdy — not flimsy at all. The cotton is thick and tightly wound, which makes them more effective for cleaning and touch-ups without coming apart. I really appreciate that they’re made from organic cotton, free from dyes or harsh chemicals. They’re easy to hold and use, and I love knowing I’m choosing something cleaner and better for my skin and the environment. Pros: • Thick and tightly packed cotton tips • Effective and easy to use • Made from organic cotton — no chemicals • Sturdy paper sticks • Eco-friendly packaging Cons: • Slightly pricier than generic brands, but the quality makes it worth it Overall: Soft, durable, and chemical-free — an excellent choice for anyone who values clean, effective, and eco-conscious personal care items

Soft, durable, and perfect for beauty and self-care routines
Size: 500 Count (Pack of 1)
These organic cotton swabs are my go-to for just about everything. They are soft but sturdy, so they do not bend or leave fuzz behind like cheaper ones sometimes do. I use them for cleaning around my eyes when removing makeup, fixing winged eyeliner, and even cleaning around my ears. They also come in handy for little touch-ups when painting my nails. I love that they are made with organic cotton and are completely chlorine-free, which makes them feel safe and gentle for everyday use. The quality really stands out, and the large pack lasts a long time. Hack: dip one in acetone to clean around your nails after painting for a quick, salon-style finish.
