Frequently Asked Questions

LIFEFACTORY BOTTLE PRODUCTS

What are the benefits of glass? Why should I buy a glass bottle over a plastic or metal one?

Glass has been a trusted material for centuries. It is one of the greenest materials on the planet, is 100% recyclable and is safe. Unlike plastic, when using glass, you don’t have to worry about harmful chemicals like BPA/BPS leaching into your liquids. Not only does your water taste better coming out of a glass bottle, because there is never a plastic or metallic taste, but Lifefactory reusable glass bottles also benefit the environment. Bottled water creates and enormous amount of waste, so do yourself a favor, choose a Lifefactory reusable glass bottle, and taste life!
Our patent-pending silicone sleeves were designed not only to look stylish but also to protect the bottles and help prevent them from breaking. The material and design combine to improve the bottle’s tactile quality and grip, which prevents bottles from becoming slick with condensation (or sweat, for athletes) and reduces the potential for breakage.
Our sleeves are made of medical-grade silicone, which is non-toxic and has been strength-tested for durability. Silicone is made from silica, the most common constituent of sand. It is a great alternative to plastics, which can leach chemicals, and to rubber or latex, to which some people are allergic.
A Lifefactory bottle is the combination of a glass bottle and complementary silicone sleeve designed in tandem. We only sell the complete package because that’s the only way to ensure the sleeve fits perfectly—plus it’s the only way we could attain our exceptional standards of quality. That’s why we don’t sell sleeves separately. We could never be sure that they would fit other bottles precisely.
All components of every Lifefactory bottle—the glass bottle itself as well as the sleeve and cap (or nipple)—are dishwasher safe or can be hand washed.

Lifefactory beverage bottles are made from soda lime glass. This is the same container glass used for wine bottles and other food storage containers. It is strong but not impervious to rapid temperature changes or impact. Like any bottle, it will expand and crack if left in the freezer or hit with boiling water.

DO NOT PUT OUR BEVERAGE BOTTLES IN THE FREEZER.

Lifefactory baby bottles are made from borosilicate glass. Borosilicate glass is known for its superior durability, chemical and heat resistance, and is excellent for use in chemical laboratory equipment and cookware. This allows the baby bottle to go from the freezer to boiling water pot without incident.

No, you can leave the sleeve on the bottle and wash the whole thing in the dishwasher. If you wish to remove the sleeve, it comes off best in warm, soapy water or with rubbing alcohol.

We do not accept returns of used products (unless they are somehow defective). Bottles that are damaged due to human miscue and gravity (e.g., dropped and broken) are not considered defective and are not eligible for refund or exchange. We do sell replacement glass for all sizes of our bottles.

Our glass baby bottles and silicone sleeves are all microwave safe. We get asked by lots of moms if it is OK to use a microwave to warm up milk or formula in our glass bottles - the answer is yes. Please remove tops and nipples before microwaving. Please test the temperature to ensure that it is safe to drink. We also recommend shaking the liquid before testing the temperature to eliminate the hotspots that can occur with many microwaves. Some of our labels and inserts state that our products are not intended for use in a microwave oven. This is a general statement because our bottles are not specifically developed as cookware/bakeware.

LIFEFACTORY BABY BOTTLES

Glass is clearly a better choice for baby bottles. Plastic bottles can leach chemicals into milk or juice (including BPA/BPS); glass does not. Plastic bottles can scratch, and scratches can harbor bacteria—glass does not. And plastic bottles typically end up in landfills when their useful life is over; glass is recyclable and reusable, and is better for the environment.

Most parents like the idea of using glass but worry about breakage. Lifefactory offers a solution by combining a sturdy glass bottle with a custom-designed silicone sleeve to protect the glass from breaking.

At Lifefactory, we are very concerned about infant safety. We have voluntarily had our bottles tested for safety and integrity by an independent third party lab, Bureau Veritas. The bottles are in compliance with the requirements of CPSIA 2008 and 16 CFR 1500 in the United States. The bottles are EN 14350 compliant in Europe.
It’s true that Lifefactory baby bottles are somewhat more expensive than some products, but we believe the combination of safety, quality, and design makes them an excellent value. Consider our materials: Borosilicate glass costs more but makes our baby bottles stronger and thermal shock resistant. The silicone sleeve (the hallmark of our bottles, which gives them their distinctive look, improves their “gripability,” and helps prevent breakage) is much more expensive to manufacture than plastic—particularly the thick, high-grade silicone that we employ. Additionally, we use top-quality, FDA-approved plastic for our caps and rings, and our French nipples are medical grade silicone; both of these factors affect product pricing. A final contributor to the price of Lifefactory bottles is our commitment to rigorous product testing, which ensures safety, durability, and minimal environmental impact.
Boil or run the bottle through the dishwasher initially to sterilize. All parts are dishwasher-safe, or they can be hand-washed. The bottle and sleeve may be boiled together. You don’t need to remove the sleeve to wash the bottle, but if you wish to remove the sleeve, it comes off best in warm, soapy water. Nipples should be washed on the top rack of the dishwasher only.
Yes, our bottles have a traditional venting system, in which ridges are located on the flange of the nipple. Tightening the ring too much will prevent ventilation and may cause nipple collapse.
Our nipples are made of silicone produced in France, where our manufacturer is that country’s leading supplier of nipples. The nipples that come with our 4 oz. bottles are Stage 1 (0-3 months), and those that come with our 9 oz. bottles are Stage 2 (3-6 months).
Yes. All of our nipples—Stage 1 (0-3 months), Stage 2 (3-6 months), Stage 3 (6+ months), and the Y-cut nipple—are available at our online store. You can also check with your local Lifefactory retailer for availability.
Yes, any standard size nipple will fit on our bottle. Wide neck nipples will not fit.
The difference between the various nipples is flow rate, which is determined by the size of the opening. As it is difficult to distinguish the hole size on a nipple by simply looking at it, we recommend washing the nipples separately according to Stage, or not opening new nipple packages until the nipple Stage that it contains is appropriate for use. Our nipples are not labeled according to Stage for manufacturer-related reasons.
We sell replacement glass bottles, silicone nipples, solid caps for breast milk storage, and caps/ring/stopper sets. Find them at our online store.

LIFEFACTORY BEVERAGE BOTTLES

In our first major product line extension, we’ve introduced a product for adults: 22 ounce (650ml) and 16 ounce (450ml) glass bottles with removable silicone sleeves that are ideal for people who carry water with them in the car, outdoors, in the office, or at the gym—or even for use at home. If you typically use bottled water, the Lifefactory Beverage Bottle is perfect for you.
Lifefactory bottles can be initially sterilized in a dishwasher (all parts are dishwasher-safe) or can be handwashed. You don’t need to remove the sleeve to wash the bottle, but if you wish to remove the sleeve, it comes off best in warm, soapy water.
