The 52mm 99-UVBTS UV Filter is Chiaro�s top-performing protective UV filter offering 99% light transmission. It�s ideal for photographers who demand the highest-quality glass and other essential features for uncompromised image fidelity and premium construction.
To achieve superior 99% light transmission, Chiaro uses highly-polished Schott glass, multi-coating, and additional advanced elements that improve the filter�s light transmission. Resistance coating helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. A durable brass filter ring is designed to screw on and off effortlessly, and it�s thin to prevent vignetting when used with wide-angle lenses. Side knurling is crafted to help ensure that you�ll have a firm grip when attaching or removing your filter.
Image quality is what matters most at Chiaro. The company has tested and combined many features and essentials to achieve superior image quality and the highest light transmission. To help take the confusion out of selecting a filter, Chiaro prominently displays the light transmission levels so that you can choose the perfect filter for your lens and photo session.
- 99% Light Transmission
- Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished Schott glass and advanced coatings, Chiaro can offer a 99% transmission rate, which is the highest possible transmission rate for glass. And the company verifies the ratings with ISO certified lab testing.
- Resistance Coating
- The layers of advanced resistance coating on the filter are designed to allow you to easily clean your filter. Water beads up and rolls off your filter, and oil and fingerprints can come off with a gentle wipe. Dust and debris won't adhere to the filter and can be removed with a puff of air.
- Polished Schott Glass
- Glass that's polished to perfection is essential to achieve a high level of light transmission. The Schott glass in this Chiaro filter is highly-polished for flatness that ensures superior optical clarity.
- Multi-Coating
- Multi-coating enhances light transmission to the demanding level set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images.
- UV Protection
- The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.
- Brass Construction
- The durable brass filter ring offers a substantial, premium feel. The unique properties of brass minimize the chance of jamming or binding when you're screwing the filter onto your lens or stacking filters.
- Slim Design
- Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.
- Top and Side Knurling
- In addition to top knurling, Chiaro added side knurling that helps offer better options to grip the filter when you're attaching and removing it, or when you're stacking filters.
- Secure Attachment
- It takes two full turns to mount the filter on your lens. This feature will securely hold your Chiaro filter through the most demanding photo shoots.
- Front Threads
- The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.

Works well
This stuff is pretty great I bought it for attaching tomato plants to the fence where the stems were too big to fit my smaller clip ties and even in our strong winds none of the ties have come undone so far

Effective and functional air purifying
Style: Medium Room Air Purifier, Style: Medium Room Air Purifier
This Amazon Basics model AC2224A Air Purifier is a really capable machine with a somewhat unique filter. I ordered it when it was on special and decided to give some detail on the features to help folks who might be new to air purifiers. The filter weighs in at just over 1lb. That's actually pretty heavy for the size. The filter does the standard 3 things people expect, pre-screen, hepa, active carbon adsorption, but it's a little unique in how it is configured. The pre-screen is straight forward and permanently attached to the outside. It should catch big stuff like pet hair to help stretch out the more expensive layers. Most other filters run a single layer of hepa then separately on the inside run a layer of activated carbon - either as mesh or pellets. Here the filter stitches the hepa and the active carbon together. The active carbon is actually small chunks about the size of sugar crystals layered inside. (yes, I found the end and cut off a pieces to check it out). That actually is a very thoughful way to do it. Activated carbon is structurally changed in the factory to increase its surface area. It's a process you can't replicate at home. The activation allows it to adsorb molecules that cause odor and VOCs. I've given you an illuminated photo of the inside of the filter so that if you can zoom in you'll see the random strands which the hepa standards require. Random strands improve filtering and add strength for the filter. The risk with running a layered filter like this is that if it's constructed poorly it will block airflow. I can check those aspects and on high speed the machine pulls under 30watts and puts out just shy of a 9mph air flow. That's good work. Air flow does create air noise which I measured at 65db directly on top of the machine. It drops another 10db a foot away. On the sleep mode I get 42db on top and that actually drops below the 30db I can measure once you're a foot away from the machine. So, it's capable of power and of being quiet. The last thing is the automation. There is an air sensor on the back by where the cord plugs in that measures the PM2.5 levels. I know what mine are (I have multiple purifiers and sensors), so it doesn't surprise me in the least that on auto the machine drops down to the lowest level. You can also turn on a light that then adds a color to indicate the air purity. I use either essential oil or incense to test the sensor. This was very responsive and noted the essential oil mist I was diffusing right away. It turned the light red and sped to its highest level. Once it had cleaned up the issue it slowed back down and returned to its peaceful green color. It gives solid performance that is in no way basic. Plus, there's the added advantage that you're familiar with the company behind it.

Fresh Air, Quiet Performance, and Easy Setup
Style: Medium Room Air Purifier
Great air purifier! It was super easy to set up and started working right away. The noise level is low, even on higher settings, and the air in my room feels noticeably fresher. It’s compact, looks nice, and fits well in smaller spaces. Definitely a solid buy if you want something simple and effective.

Good air purifier - make sure you actually unwrap the filter lol
Style: Medium Room Air Purifier
I'm an idiot and didn't realize the filter that comes already inside it was in there wrapped in plastic for some reason that surpasses my understanding (the whole unit was already wrapped in plastic, why is the filter, which is inside the plastic-wrapped unit, also wrapped in its own separate plastic?? As if we need more plastic in the world...). Anyway, I didn't look inside cuz I thought the filter would just be installed in there and I plugged it in and cheerfully ran it for months til it told me it was time for replace the filter then bought a second filter and went tk take my old one out only to realize I hadn't been filtering anything all that time 😅 oops. Lol. So yeah, make sure you unwrap the filter. Otherwise it's a good little air purifier. Now that the filter is actually installed right, I notice it kicks up higher when we cook or do anything that would lower air quality, so it does seem to be detecting that properly! My allergies do seem better overall. It's pretty quiet when it's on low, but does get loud when it kicks up. I'm OK with that since it pretty much only happens when we cook or if I just put out a candle or something.
