Intelligent Air Purifier

The Most Complete Air Purifier on the Market - Advanced Sensor Technology and Six Leading Technologies.

Sensor Technology: Sensors are in place to monitor air quality, detect certain types of pollutants, and to indicate when the filter or bulb need to be replaced.

Six Leading Technologies: With six air purification functions, there is a technology for virtually every type of airborne pollutant.

Technologies include HEPA filter, activated carbon filter, ionizer, germicidal UV light, washable electronic dust collector and washable pre filter.

Odour, dust and allergen sensors let you know when certain pollutants are detected, such as cigarette smoke, chemicals, dust mites, pollen, pet dander, mold spores and many more.

The clean air monitor tells you how clean or polluted the air is. If you select "Automatic" mode, the Intelli-Pro will automatically adjust the settings accordingly, reducing electricity usage if the air is fairly clean.

Diagnostic sensors indicate when to replace filters, and when to clean the metal dust collector grid.

The UV light and negative ion indicators let you know that these functions are working, and indicate when the UV lamp needs to be replaced. 1. Washable Pre Filter. The air first enters pre filter, capturing the largest particles, which enhances the durability and performance of the other filters.

2. Washable Dust Collector Plates. The electrostatically-charged dust collector grid traps particles and pollutants like a magnet. This is similar to Friedrich C-90A, which is Consumer Reports' top-rated air purifier. Unlike the C-90A, the Intelli-Pro has multiple other leading technologies.

3. Activated Carbon Filter. The best type of air filter for trapping chemicals, gases, odours and cigarette smoke. According to Penn State Dept. of Aerobiological researchers, carbon filters ser

After taking lot of inspiration from different people, I bought Vintage Friedrich Corygon Compur shutter lens.
The focussing distance was little longer, and there was a need of Lens movement (instead of mechanism within lens). I tried to use one broken lens assembly for focussing. But my setup didnt work.
After carefully looking the lens and trying different threads, I found out the lens has 39mm mount. I bought long time back, M42->M39 adaptor. And everything fall in line after that.
And I come up with this idea (and now I found few people did this before),
And surprisingly, the setup is handy.

The cool start of a hot and humid day at my local river. Long (!) periods of rain resulted in "autumnal" mornings at the peak of summer such as in this scene at the river bank.
