Home & Kitchen Products
How did we get our start?
We started as gardeners and composting enthusiasts looking for better-designed solutions for the modern kitchen. When we couldn’t find them, we made them.
What makes our products unique?
Our products blend minimalist style with practical innovation. Each bin is built to last and designed to fit seamlessly into your space.
What problem are we solving?
We help households manage waste cleanly and effortlessly. Whether it’s a compost bin with dual-filter odor control or a hands-free trash, RED FACTOR is here to make your home more organized—and more beautiful.
Completely Odorless – These RED FACTOR indoor compost bin replacement filters are equipped with activated carbon technology that neutralizes bad smells even in hot summer days. You can keep adding food scraps (such as fruits, vegetables, coffee grounds, egg shells, tea bags etc.) to your compost bucket without worrying about any bad smells.
Great Value for Money – Includes 8 compost bin carbon replacement filters (4 round and 4 square). Each filter lasts 3-4 months at least so you can enjoy over a year’s worth of odor free composting.
Perfectly Sized – Perfectly sized to fit most compost bins out of the box. Can be cut to size easily with scissors if smaller size is intended. The round carbon filters are 6.50-inch in diameter while the square filters are about 4.5-inch in length each side. Unlike other filters, these are 0.4 inch (10 mm) thick. This ensures no smell will ever escape your indoor compost bucket while pores encourage smell free ventilation which is essential for composting.
Easy to Use – Old filters can be replaced quite easily with these RED FACTOR filters. Just pinch the old filter from the side to remove from the lid. Clean the lid before inserting the new one. Insert the new filter making sure its straight and all opening is covered. These filters are equipped with active charcoal ingredient so please do not rinse or wash.
100% Satisfaction Guarantee – We are a small independent company who pride ourselves on the high level of customer care that we offer. At RED FACTOR, we believe in designing high quality yet affordable products that improve lives. If for any reason you are not satisfied with your purchase, just contact us and we’ll send you a refund or exchange the product.

Replacement filters for Red factor Counter Compost Container
Perfect fit for the Red Factor Container counter I bought a few months ago. Good filters that keep the smell out and pests to a minimum!

These filters are the best!!
I have a gallon compost can and these fit perfect in the lid of my can. I have ordered other brands on Amazon and those could not compare to these on fit or quality. These are thicker and there is no foul odors that escape. Not even onion, garlic or banana peels!! Packaged great and arrived quickly. Buy these!! You wonât be disappointed.

Perfect filters
We just received them and they were so easy to install. I like the idea of supporting a couple as they creat a new business for themselves. We are 100% happy with these filters and the cost is very fair.

GREAT Value for compost filters
I am impressed with the thickness of the charcoal filters. They fit my kitchen compost can perfectly. I use the double up , one round and one square and Iâm so glad to find these as one package together. I will definitely be a repeat customer and I hope others will find composting a part of their lives.

Damlanur Bilgin –
Bu filtreleri kutusuyla birlikte aldım ve bir yıldan uzun süredir kullanıyorum. Hem kutudan hem de filtrelerden çok memnunum. Hiç koku yapmıyor ve filtreler çok uzun gidiyor. Satıcının ürünle birlikte gönderdiÄi açıklamalar çok bilgilendirici. Tavsiye ederim kesinlikle.
