Every product page lists the OEM part numbers and model numbers the part replaces. Match your model number against that list before you order; manufacturers often change part numbers from year to year even when the part stays the same, so the list matters more than the number on your old part. If you are not sure, send the brand and model number to support@thinkcrucial.com and we will match the part for you.
Most vacuums have a data plate with the model and serial number. On upright vacuums it is usually on the back of the machine behind the hose and attachments; on canister vacuums it is usually on the bottom of the unit. Other appliances typically carry the plate on the base or the back.
No. Think Crucial parts are compatible replacement parts that we engineer to fit and work in a specific appliance, using the original part as the reference. Brand names on our product pages are trademarks of their owners and are used only to say what a part fits; we are not affiliated with or endorsed by those manufacturers.
It may. Each manufacturer sets its own warranty terms, and using a non-OEM part or descaler can affect coverage. Check your warranty terms if that matters to you.
We do. The vacuum filters, bags, belts and hoses, the air-purifier and humidifier filters, the AeroGarden-compatible grow bulbs, and the descalers and cleaners are designed, made and shipped by Think Crucial. We do not resell other companies' parts. Read more on our about page.
We start from the OEM part number and the models it serves, then take the measurements that decide whether a part works: outside dimensions, mounting tabs and seal surfaces, filter media type and depth, belt length and profile, hose diameter and cuff fit. The part is made to those measurements and the fit is checked before it is listed.
Most manufacturers recommend every 3 to 6 months, and sooner with heavy use or if anyone in the home has allergies. Many newer vacuums use more than one filter, so check your manual for each location. Browse vacuum filters.
With use the belt stretches and loses tension on the brush roller, so the roller turns more slowly and leaves debris in the carpet. A belt can look fine and still be slipping, so replacing it about every 3 months keeps the vacuum working properly. Browse vacuum belts and parts.
Most manufacturers recommend every 3 to 6 months for the main filter, and more often for allergy or asthma sufferers. Carbon pre-filters, which trap larger particles and odors before the main filter, are usually changed every 2 to 4 weeks. Browse air purifier filters.
Most of the line is built on food-grade citric acid at 25% to 44%, which dissolves limescale and rinses out without residue. Some formulas add lactic acid, and formulas for appliances with aluminum boilers or nickel-plated parts are buffered with sodium citrate so they dissolve scale without attacking the metal. There are no phosphates, chlorine bleach, EDTA, borates, fragrance or dye, and most formulas are two to four ingredients. See the full range at cleaners and descalers.
They are formulated by us and bottled in small batches in Hollywood, Florida, with US-sourced ingredients.
For an electric kettle, add 2 tablespoons of concentrate, fill with water and boil. For a dishwasher, pour 2 tablespoons into the bottom of the empty tub and run a hot cycle with no detergent. For a coffee maker, add 2 tablespoons for soft water or up to 4 tablespoons for hard water to the reservoir, top up with water and run the descale cycle. Step-by-step guides: kettle, dishwasher, coffee maker.
Water hardness sets the schedule. As a baseline, descale a kettle every 2 to 4 months, a dishwasher monthly, and a coffee maker every 1 to 3 months. On hard water move to the short end of each range; on soft or filtered water the long end is enough.
Vinegar is acetic acid, which is weaker on limescale than citric acid, and its smell and taste linger through several rinses. Bleach does not dissolve scale at all, is not safe in an appliance you drink from, and must never be mixed with an acid descaler.
