Kirby bags are sold at big-box retailers, online marketplaces, and directly from Kirby dealers
You can find Kirby vacuum bags at Walmart, Target, Amazon, and eBay, though stock varies by location and model. The most reliable source is usually a Kirby authorized dealer in your area, because they stock bags for multiple Kirby models and can confirm which bag fits your machine before you buy. Costco and Sam's Club sometimes carry Kirby bags if you have a membership, but availability is seasonal and unpredictable.
Buying directly from Kirby's official website (kirby.com) guarantees you get the correct bag for your model, and you avoid counterfeit products. Prices are typically higher than retailers, but you know what you are getting. Local vacuum repair shops also stock Kirby bags and can often order bags for older models that big retailers no longer carry.
Key Takeaways
- Authorized Kirby dealers are the fastest way to get the right bag because staff can match it to your specific model number.
- Amazon and Walmart carry Kirby bags at lower prices than Kirby's official site, but check the seller rating and read reviews to avoid counterfeit bags.
- Costco and Sam's Club sometimes stock Kirby bags at competitive prices, but selection is limited and changes seasonally.
- Vacuum repair shops can order bags for older Kirby models that major retailers have stopped carrying.
- Always check your Kirby's model number before ordering, because different Kirby models use different bag sizes and attachment systems.
How to find your Kirby model number
Your Kirby's model number is printed on a silver sticker on the back or underside of the machine. Common Kirby models include the Sentria, Avalir, G6, G5, and G4. Write down the full model number before you shop, because it determines which bag will fit. A bag for a Sentria will not work on a G6, even though both are Kirby machines.
If you cannot find the sticker or the number is worn off, take a photo of your vacuum and bring it to a Kirby dealer. They can identify the model by sight and tell you exactly which bag you need. This takes five minutes and costs nothing.
Authorized Kirby dealers near you
Kirby maintains a dealer locator on its website where you can enter your zip code and find authorized shops within a few miles. These dealers stock bags in inventory, so you can walk in and leave with the right bag the same day. They also sell other Kirby parts — belts, filters, brushes — and can answer questions about maintenance.
Authorized dealers typically charge more per bag than Amazon or Walmart, but the difference is usually two to four dollars. The trade-off is certainty: you know the bag is genuine, it fits your model, and if there is a problem you have a local shop to return to. Many dealers also offer repair services if your Kirby stops working.
Online retailers and what to watch for
Amazon has the widest selection of Kirby bags and often the lowest prices, but third-party sellers sometimes list counterfeit bags alongside genuine ones. Before you buy, check the seller's rating and read the most recent reviews. Look for reviews that mention whether the bag fit correctly and whether it was authentic. Bags sold by Amazon itself (not a third-party seller) are more likely to be genuine.
Walmart's online store and in-store inventory vary by location. You can check availability on Walmart.com and either pick up in store or have it shipped. eBay has many sellers offering Kirby bags, but again, check the seller's feedback score and read reviews mentioning authenticity. Bags from eBay sellers with fewer than 95% positive feedback are riskier.
Costco and Sam's Club occasionally stock Kirby bags at prices lower than other retailers, but you must have a membership and selection is unpredictable. If you shop at either store regularly, it is worth checking their website or asking a staff member whether Kirby bags are currently in stock.
Kirby's official website and direct ordering
Kirby.com sells bags directly to consumers and guarantees authenticity. You enter your model number, and the site shows you compatible bags. Shipping usually takes five to seven business days. Prices on Kirby's site are often ten to fifteen percent higher than Amazon or Walmart, but you avoid any risk of receiving a counterfeit product.
Kirby's website also lists authorized dealers by state, which is useful if you want to buy in person. The site has a customer service phone number if you are unsure which bag fits your model.
Vacuum repair shops and specialty retailers
Independent vacuum repair shops in your area almost always stock Kirby bags, even for older models. These shops depend on repair work and parts sales, so they maintain inventory for machines that big retailers have stopped carrying. If you have a Kirby from five or ten years ago and cannot find bags at Walmart or Amazon, a local repair shop can usually order one within a few days.
Repair shops also know common problems with each Kirby model and can advise you on whether a bag is the right choice for your machine. Some shops offer a small discount if you buy multiple bags at once.
Comparing prices and avoiding counterfeits
Kirby bags typically cost between eight and eighteen dollars depending on the model. Authorized dealers and Kirby's official site are usually at the higher end. Amazon and Walmart are usually five to ten percent cheaper. Costco and Sam's Club occasionally offer the lowest prices, but only if they have stock.
Counterfeit bags are a real problem on Amazon and eBay. A counterfeit bag may fit loosely, tear easily, or not seal properly, which means dust escapes into your motor and shortens the vacuum's life. To avoid counterfeits, buy from sellers with high ratings, read recent reviews mentioning authenticity, and check whether the bag packaging looks professional. Genuine Kirby bags have clear printing, sturdy cardboard, and a Kirby logo on the package.
Frequently Asked Questions
Can I use a generic vacuum bag instead of a Kirby bag?
Generic bags sometimes fit Kirby machines, but they often do not seal properly and allow dust to escape into the motor. Kirby bags are designed specifically for Kirby's suction system and filtration. Using a generic bag may damage your vacuum over time. It is safer to buy the correct Kirby bag.
What if I order a bag and it does not fit?
If you ordered from Amazon or Walmart and the bag does not fit, you can return it for a refund or exchange. If you bought from a Kirby dealer or Kirby's website, contact them with your model number and they will send the correct bag. Always keep your receipt and the original packaging in case you need to return it.
Are Kirby bags reusable or disposable?
Kirby bags are disposable. When the bag is full, you remove it and throw it away, then insert a new one. Some older Kirby models used cloth bags that could be emptied and reused, but modern Kirby machines use paper bags designed for single use. Reusing a full bag reduces suction and can damage the motor.
How often do I need to buy new Kirby bags?
This depends on how often you vacuum and the size of your home. Most households replace a Kirby bag every two to four months. You will notice suction dropping when the bag is full. Some Kirby models have a full-bag indicator light that tells you when to change it.
Can I buy Kirby bags in bulk to save money?
Yes. Authorized dealers often give a small discount if you buy five or ten bags at once. Costco and Sam's Club sometimes offer bulk pricing. Buying in bulk makes sense if you have a large home or use your Kirby frequently, but bags do not expire so you can store extras for months.
