NatureMill ULTRA Automatic Indoor Composter

The NatureMill ULTRA is the latest, most advanced NatureMill model. The ULTRA has a number of improved features over previous models including a greater capacity, a fingerprint-free stainless steel exterior and a quieter motor.

The NatureMill ULTRA is a "continuous-use" composter. This means you can continue to add food scraps while the composting process is working. The bottom chamber holds the finished compost until you are ready to use it. A red light will display when the bottom chamber is full.

The NatureMill ULTRA product highlights include:

• Produces approximately 2 gallons (6L) of compost every two weeks, depending on use
• 4 gallon (15 L) weekly capacity: perfect for a family of 4-5 people
• Genuine stainless steel, fingerprint-proof exterior
• Quiet: operates at an average of 47 decibels
• Heavy-duty mode for faster composting (increased heat and mixing)
• Lifetime filter never needs replacing
• 1-yr product warranty

It’s easy to use the NatureMill. Simply lift the lid, and dump in your food scraps. The composter will automatically mix, heat, and aerate these scraps in the upper chamber. Food scraps are then transferred to the lower chamber where it continues to compost. The moist air (most of the food’s weight and size is water) is sucked out through a carbon filter which also removes the composting odors. After two weeks, a red light will come on to let you know it’s time to remove the lower chamber and put the compost in your garden or on your potted plants.

Getting to Know Your NatureMill

Everyday Use of Your NatureMill

Warranty

The one-year warranty includes: free replacement parts, repair by field technician, or replacement of entire unit. Return an unused unit within 30 days for a full refund. Due to the biological implications of composting, returns generally not accepted after contact with food waste.

Cleaning & Maintenance

Maintenance of your NatureMill is easy and minimal. Wipe the hopper and exterior with a moist towel. Rinse the cure tray and drip tray when you empty them. Do not disturb the compost cultures in the reactor chamber. Do not use soaps or chemicals. p>

Improvements over earlier NatureMill models

• Stronger Motor: Motors used to jam on large or hard composting tasks, so we doubled the motor strength, without increasing energy consumption. A new grinding feature devours stubborn compost items. And if a jam occurs, the motor will try again every 4 hours until the jam clears. A new "Heavy-Duty" mode is available on Pro and ULTRA models to handle even the toughest composting challenges.
• More Powerful filter: Our compost bin engineers have refined the "secret recipe" for compost. We've increased air filtration with a new quieter pump and a new carbon filter. The carbon filter has a lifetime guarantee on Pro and ULTRA models. More even heat circulation ensures that corners and edges compost effectively.
• Energy Saver Mode: This convenient feature enables you to reduce NatureMill's energy consumption by 75%. Now you can reduce mixing, heating, and air flow rate when you go on vacation, or if you just do not have much to compost.
• The Little Extras: Instruction manuals can be so intimidating - so we added a Quick Start Guide to make operation easier than any compost tumbler. Some people live in rainy places - so we upgraded the waterproofing of the entire unit. These features represent years of product design evolution!

More Detail

• No worms, bugs, or trash odors: Natural compost cultures consume waste quickly, without odors. They produce a mild aroma like sourdough, mushrooms, or straw. Balance the chemistry by adding sawdust to increase "brown" content, and baking soda to reduce acidity (both are included). A fan draws air into the machine, providing oxygen to the cultures. A powerful carbon filter removes any lingering odors.
• Use it anywhere: Fits inside any standard cabinet. Keep it in the kitchen, a garage, or laundry room. Use it outdoors, even in the snow, rain, or freezing temperatures. Keep the power supply dry, using a weather-rated power outlet (available at most hardware stores).
• Endless supply of compost: Empty the cure tray when the indicator light comes on - roughly every two weeks. More than 70% of the initial waste disappears into thin air -- literally -- as compost cultures convert it into water vapor. What's left is a very concentrated compost fertilizer. Fresh compost has a mild organic aroma, which people often describe as damp wool, sourdough bread, or mushrooms. You can use it outdoors immediately, or leave it in a bucket or tote until you are ready to garden.
• Compost is the best fertilizer you can give your garden: Food compost is very high in nitrogen, which is essential for growing healthy plants. Spread over the soil surface, like mulch. Nutrients will gradually enter the soil during watering and annual tilling. Use it on your garden, lawn, shrubs, trees, or indoor potted plants. One batch of compost is enough for 10-40 sq ft (1-4 sq m) of a lawn or garden, applied once or twice per year. Or use one batch per tree. You can also infuse mature compost with water to brew "compost tea" liquid fertilizer.
• Great for the environment: Energy use is just 5 kwh / month, or about $0.50/month - less than a garbage truck would burn in diesel fuel to haul away the same waste. A NatureMill composter recycles its weight in waste every 10 days, diverting over two tons of waste from landfills over its life. This reduces emissions of methane, a harmful greenhouse gas produced when organic matter decomposes in oxygen-starved landfills. NatureMill is made from recycled and recyclable materials. Every NatureMill composter meets or surpasses the stringent California Energy Efficiency Level IV - the most stringent energy standard in the world.
