Review: Eliminates Filter Odor! - We are in Michigan, which has a whirlwind of humidity fun throughout the winter months. Depending on the year, we have a VERY dry house the entire season but other years, there's an ebb and flow with warmer than normal temps. This has made it challenging for us to maintain the four humidifiers that we typically bring out 3-4 months per year. If they are running nonstop, I've learned that the filters last longer but when humidity ebbs and flows, we get a faster accumulation of buildup and need to replace filters frequently. I've tried chemical additives, vinegar, and rinsing filters off to maximize life. It's super annoying and time-consuming and has been minimally effective. Last year I tried these on a whim and was delighted at how well they work. We had a mild winter that didn't require humidifiers to be constantly running and ALL of our filters remained clean for over a month. The typical pink/black/brown slimy and odorous filters that needed to be changed sometimes biweekly, we had a collection of slightly colored filters. This came at the end of our winter, so I pitched the filters but have high hopes for a much smoother experience going into another Michigan winter. I wish I had given these a chance before. I was a skeptic but no more as these have earned a coveted space in our Subscribe and Save lineup for annual home maintenance items. Review: Seems to help prevent how fast pink slime bacteria forms in water left in container - Works, but I could see pink slime bacteria starting after I didn't wash the humidifier as soon as I should have. Probably would have been worse without this, though, so I'll keep buying them. ## Features - Fight mold growth: PureGuardian GGHS15 Aquastick humidifier water cartridge helps reduce the growth of mold and odor causing bacteria in the water of a humidifier tank and can be used in both evaporative ultrasonic humidifiers - Only one stick needed: One Aquastick can be used in humidifiers with a tank that is up to one gallon in size. For humidifiers with a capacity of one to two gallons, use two Aquasticks - For best results: PureGuardian recommends to clean your humidifier tank according to the manufacturer's instructions before using the AquaStick and to use clean, fresh water. Replace every 90 days - Easy to use: Simply drop the GGHS15 AquaStick universal humidifier water cartridge. Keep your humidifier's mist clean and functioning properly with ultimate filtration and purification - PureGuardian: Guardian technologies offers a full range of small appliance-based solutions for happier and healthier lives at home, focused on creating powerful, safe and innovative technologies to help facilitate healthier, happier home environments ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0055522EM | | Best Sellers Rank | #56,427 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #54 in Humidifier Accessories | | Brand | PureGuardian | | Brand Name | PureGuardian | | Capacity | 2 Gallons | | Color | blue | | Control Method | Touch | | Customer Reviews | 4.4 out of 5 stars 15,629 Reviews | | Filter Type | Humidifier Treatment | | Global Trade Identification Number | 00895916000189, 10895916000186 | | Included Components | PureGuardian GGHS15 Aquastick Humidifier Treatment, 2-Pack | | Item Dimensions D x W x H | 0.68"D x 0.68"W x 2.75"H | | Item Shape | Round | | Item Type Name | Guardian Technologies GGHS15 Aquastick Antimicrobial Humidifier Treatment, 2-Pack, Pure Guardian Humidifiers, Evaporative Humidifier Water Tanks | | Item Weight | 9.07 g | | Manufacturer | Guardian Technologies, LLC | | Material | Plastic | | Model Name | Guardian Technologies GGHS15 Aquastick Antimicrobial Humidifier Treatment, 2-Pack, Pu | | Model Number | GGHS15 | | Operation Mode | Ultrasonic | | Other Special Features of the Product | Helps to keep your humidifier tank cleaner longer | | Part Number | GGHS15 | | Power Source | Ultrasonic | | Product Dimensions | 0.68"D x 0.68"W x 2.75"H | | Room Type | Bedroom | | Runtime | 0 minute | | Smart Home Compatibility | Not Smart Home Compatible | | Special Feature | Helps to keep your humidifier tank cleaner longer | | UPC | 784922207494 895916000189 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** PureGuardian - **Capacity:** 2 Gallons - **Color:** blue - **Operation Mode:** Ultrasonic - **Special Feature:** Helps to keep your humidifier tank cleaner longer ## Images ![Aquastick, Universal, Genuine Guardian Technologies Antimicrobial Humidifier Treatment, Ultrasonic & Evaporative, Fits All Brands, Reduces Odors, 2 Count (One Pack of Two), GGHS15 - Image 1](https://m.media-amazon.com/images/I/81dXXb8rtVL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Should I use this with a Demineralization Cartridge?** A: Yes. They serve different purposes. Demineralization Cartridges: Since most consumers do NOT buy distilled water for the humidifier/vaporizer, the manufacturer has created the demineralization cartridge feature to remove the sediment from tap, well or spring water. Even if your home has “purified” water, there is a certain amount of calcium, lime or other minerals that are in the water- safe for us to drink, but as the water is evaporated, these minerals clog up the machine. Aqua Stick: Because fungi spores, mold spores and bacteria are in tap water already and also travel trough the air landing in the water to eventually grow and gum up the functionality and health benefits of the humidifier, the aqua stick is advertised as a means of reducing that kind of buildup. If you have ever noticed the slimy film that develops in water that sits too long, you know what I am talking about. If this slimy residue is in your tank, the mold, mildew or bacteria is being released airborne in the water mist and increases the likelihood of airborne illness, allergy and asthma problems as well as just making your machine gross and ineffective. The bottom line is this: For optimum health benefits- keep the machine clean. If you want it to function properly, keep it clean. The demineralization cartridge and aqua sticks work together to keep the machine cleaner longer. **Q: How to use this?** A: Clean humidifier according to manufacturers' instructions. After cleaning place 1 or 2 aquasticks into the humidifier. For every gallon of water contained in the humidifier tank, use one stick. Replace about every 90 days. **Q: What are the 'other' ingredients listed at 99.82%? Thanks** A: A package I got from home depot says aluminum sulfate as well as silver just fyi. Also just gotta say, W. Millers sugestion is a really good one. I've been looking for a product that dosn't have mystery/less than ideal filler ingredients companies arent' required to disclose, and prevents bacteria build up like silver does. But I also want something that prevents residue and scaling from mineral deposits, which citric acid will do. This is what I will use from now on, it works great. **Q: Can these be used with water mist / steam humidifiers?** A: Check with the manufacturer of the humidifier you are looking to use the product in. These were made for Pure Guardian brand humidifiers so use in any other brand is not recommended without first speaking with a customer service representative for that company. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Eliminates Filter Odor! *by V***2 on October 4, 2024* We are in Michigan, which has a whirlwind of humidity fun throughout the winter months.

I used to have a problem with black mold in my humidifier cause we use a Woodstove one of these are season and I have had no black mold, kind of speaks for itself. ## Frequently Bought Together - PureGuardian Aquastick, Universal, Genuine Guardian Technologies Antimicrobial Humidifier Treatment, Ultrasonic & Evaporative, Fits All Brands, Reduces Odors, 2 Count (One Pack of Two), GGHS15 - The Original Humidifier Drops - Premium Food Grade Concentrate, Slows Down Residue Accumulation on Surfaces, Minimizes Scaling - Freshens Water in All Humidifier Models, 100+ Day Supply, Made in USA - LEVOIT Top Fill Humidifiers for Bedroom, 2.5L Tank for Large Room, Easy to Fill & Clean, 28dB Quiet Cool Mist Air Humidifier for Home Baby Nursery & Plants, Auto Shut-off and BPA-Free for Safety, 25H --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/1201161-aquastick-universal-genuine-guardian-technologies-antimicrobial-humidifier-treatment-ultrasonic-evaporative](https://www.desertcart.hr/products/1201161-aquastick-universal-genuine-guardian-technologies-antimicrobial-humidifier-treatment-ultrasonic-evaporative) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-25*
