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.

Clean feel and gentle on teeth
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I picked up this toothpaste because I wanted to try something a little different that focused on a more natural feel while still keeping my teeth clean, Between coffee daily meals and just normal wear I was looking for something that felt effective without being harsh, I wasnt sure how I would like a fluoride free option but it has been a nice change When it arrived the first thing I noticed was the clean simple packaging and the peppermint scent, The texture is smooth and spreads easily without being overly foamy, It has a mild mint flavor that feels fresh without being too strong or overpowering, My spouse tried it as well and said it felt less intense than typical toothpaste which was actually a positive After using it regularly my teeth felt clean and smooth without that overly stripped feeling some products leave behind, It has been gentle enough that I did not notice any sensitivity or irritation which is something I always pay attention to, The overall experience feels more balanced and not overly aggressive I also like that it does not have a long list of harsh ingredients and still manages to do the job, It fits easily into a daily routine and does not require any adjustments or special steps, The tube size is practical and easy to store For anyone looking for a toothpaste that feels gentle clean and a bit more natural this has been a good option, It keeps things simple while still providing a fresh feeling after brushing I currently highly recommend this product. However, should issues arise I will update my review accordingly.

Only toothpaste in my household
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
Love this toothpaste, no fluoride, great taste, fresh breath. Great value for the price as the tube is quite large. Only downfall if that it doesn't foam well which you will find with any toothpaste not full of nasty chemicals. Only thing my family uses.

Give it a few weeks! It works!
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I've been brushing with this toothpaste twice a day for about 3 weeks. I can see an improved whitening. My hairdresser, new one I hadn't met before, told me I have perfect teeth. Actually they're not that straight but the color of my teeth makes up for the misalignment of some of them. Flavor of toothpaste is good. Didn't cause any sensitivity for me.

Love this!
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
This toothpaste does not foam but my mouth has never felt cleaner or fresher! The taste is minty fresh and I have noticed a difference in the whiteness of my teeth since I started using it! Very effective and I highly recommend!
