If you own a Kenmore Elite 31150 upright vacuum, you already appreciate its strong suction and durable build. But even the best vacuum loses performance when its bag is full or clogged. Finding the right replacement bag is essential to keep your machine running smoothly and to trap allergens effectively. In this review, we evaluate two top-rated options: the Anewise 53294 Type O Elite Vacuum Bag for Kenmore and the Casa Vacuums 31140 31150 BU1017 BU1005 Bag + Filter Kit. Both are designed specifically for Kenmore Elite models, including the 31150, but they differ in quantity, included extras, and filtration technology. Whether you prioritize maximum filtration or a complete kit with a filter, we have you covered. For a deeper look at the vacuum itself, check out our full kenmore elite 31150 vacuum review.
Buying Guide: How to Choose the Best Kenmore Elite 31150 Bags
When shopping for replacement bags for your Kenmore Elite 31150, you need to consider more than just price. The right bag affects suction, filtration, and how often you need to change it. Here are the key factors to keep in mind.
Compatibility: Make Sure It Fits Your Model
The Kenmore Elite 31150 uses Type O (also called Style O) bags, which are interchangeable with many other Kenmore upright models like the 5068, 50105, and BU1017. However, some bags are labeled as Type U and still fit the same models. Always verify the model numbers listed by the manufacturer. The Anewise bag explicitly lists the 31150 in its compatibility, while the Casa Vacuums kit is designed for the 31140, 31150, BU1017, and BU1005. If you have a different Kenmore model, double-check before buying. For more guidance on bagged vacuums, see our Best Bagged Vacuum for Pet Hair article.
Filtration: HEPA vs Standard
Both products offer HEPA-style filtration, but the materials differ. The Anewise bag uses five layers of composite material and claims to capture 99.97% of particles as small as 0.3 microns. This is especially important for allergy sufferers or homes with pets. The Casa Vacuums kit includes 12 bags plus a separate EF-9 exhaust HEPA filter, which adds an extra layer of protection. If you prioritize air quality, the Casa kit gives you both bag and filter for a complete system.

Value: Quantity and Included Extras
The Anewise pack contains 8 bags, which is a solid supply for several months. The Casa Vacuums kit includes 12 bags plus one exhaust filter, making it a year-supply for many households. If you change bags every three months as recommended, 12 bags last a full year. The added filter is a bonus that saves you a separate purchase. Consider how often you vacuum and whether you want the convenience of a filter included.

Ease of Installation and Use
Both bags are designed for tool-free installation. The Anewise bag features upgraded self-sealing technology, which makes disposal clean and easy. The Casa Vacuums bags are standard Type U/O bags that snap into place without fuss. Neither requires any adapters or modifications. If you value quick changes and minimal mess, either option works well. Just make sure the bag is fully seated before closing the compartment to maintain suction.
Final Thoughts
Choosing between these two excellent replacement sets comes down to your priorities. If you want a straightforward, high-filtration bag at a lower upfront cost, the Anewise 53294 Type O Elite Vacuum Bag for Kenmore delivers eight HEPA bags with advanced self-sealing technology, perfect for maintaining a clean home without overspending. If you prefer a complete maintenance kit that includes both bags and an exhaust filter for year-long coverage, the 31140 31150 BU1017 BU1005 Bag + Filter Kit from Casa Vacuums offers exceptional value and peace of mind. Whichever you choose, your Kenmore Elite 31150 will continue to perform at its best, keeping your floors and air clean.
Frequently Asked Questions
How often should I replace the bags in my Kenmore Elite 31150?
Manufacturers recommend changing the bag every three months or when it appears full, whichever comes first. In 2026, with many homes seeing increased use, you may need to replace it more frequently if you have pets or high traffic. A full bag reduces suction and can strain the motor, so check it monthly.
Are these replacement bags HEPA certified?
Yes, both the Anewise and Casa Vacuums bags use HEPA-style filtration. The Anewise bag claims to capture 99.97% of particles down to 0.3 microns. The Casa kit includes a HEPA exhaust filter as well, which further improves air quality. For allergy sufferers, either option is a solid choice.
What is the difference between Type O and Type U bags for Kenmore?
Type O and Type U bags are often used interchangeably for Kenmore Elite uprights. The main difference is the shape of the cardboard collar and the bag material. Both fit the same models like the 31150, 5068, and BU1017. Always refer to the model numbers listed on the product page to confirm compatibility. For more details on vacuum types, see our Upright Vacuums category page.
Can I use these bags in other Kenmore models besides the 31150?
Yes, both products are compatible with a wide range of Kenmore upright vacuums. The Anewise bag works with models like 53294, 50690, 5068, 50105, and many more. The Casa kit fits 31140, 31150, BU1017, BU1005, and similar. Always verify your model number against the list provided by the seller to ensure a perfect fit.
