Formaldehyde ( for-MAL-di-hide, US also fər-) (systematic name methanal) is an organic compound with the chemical formula CH2O and structure H−CHO, more precisely H2C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde. It is stored as aqueous solutions (formalin), which consists mainly of the hydrate CH2(OH)2. It is the simplest of the aldehydes (R−CHO). As a precursor to many other materials and chemical compounds, in 2006 the global production of formaldehyde was estimated at 12 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings. Small amounts also occur naturally.

Formaldehyde is classified as a carcinogen and can cause respiratory and skin irritation upon exposure.

Gold is a chemical element with the chemical symbol Au (from Latin aurum) and atomic number 79. In its pure form, it is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard conditions.

Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is insoluble in nitric acid alone, which dissolves silver and base metals, a property long used to refine gold and confirm the presence of gold in metallic substances, giving rise to the term 'acid test'. Gold dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold also dissolves in mercury, forming amalgam alloys, and as the gold acts simply as a solute, this is not a chemical reaction.

A relatively rare element, gold is a precious metal that has been used for coinage, jewelry, and other works of art throughout recorded history. In the past, a gold standard was often implemented as a monetary policy. Gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard was abandoned for a fiat currency system after the Nixon shock measures of 1971.

In 2023, the world's largest gold producer was China, followed by Russia and Australia. As of 2020, a total of around 201,296 tonnes of gold exist above ground. This is equal to a cube, with each side measuring roughly 21.7 meters (71 ft). The world's consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry. Gold's high malleability, ductility, resistance to corrosion and most other chemical reactions, as well as conductivity of electricity have led to its continued use in corrosion-resistant electrical connectors in all types of computerized devices (its chief industrial use). Gold is also used in infrared shielding, the production of colored glass, gold leafing, and tooth restoration. Certain gold salts are still used as anti-inflammatory agents in medicine.

Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere.

Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores.

Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick). Nickel minerals can be green, like copper ores, and were known as kupfernickel – Nickel's copper – because they produced no copper.

Although most nickel in the earth's crust exists as oxides, economically more important nickel ores are sulfides, especially pentlandite. Major production sites include the Sudbury region, Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific, Western Australia, and Norilsk, Russia.

Nickel is one of four elements (the others are iron, cobalt, and gadolinium) that are ferromagnetic at about room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is used chiefly in alloys and corrosion-resistant plating.

About 68% of world production is used in stainless steel. A further 10% is used for nickel-based and copper-based alloys, 9% for plating, 7% for alloy steels, 3% in foundries, and 4% in other applications such as in rechargeable batteries, including those in electric vehicles (EVs). Nickel is widely used in coins, though nickel-plated objects sometimes provoke nickel allergy. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation, cathodes for rechargeable batteries, pigments and metal surface treatments. Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site.

    I am very pleased with this device. The air purification seems to work really well, the fan is quiet and moves a lot of air. Have just started using the humidifier here in MN but super easy to use. I’m surprised how much I like using the Dyson Link app, but very convenient for notifications of when to add water.

    This machine is pretty amazing. It’s very sleek looking and draws attention. At first look upon unboxing I thought it was fairly large. But I got used to this quickly. I love how it can constantly measure the air quality and adjust automatically. The humidifier function is an added bonus, although I haven’t had the need for that as it is relatively rainy in southeast Michigan. My wife who has allergies has noticed a breathable difference. The ability to control the machine from my phone is very convenient as well.

    I received this machine a week ago and it has been running non-stop since I took it out of the box. I’ve owned many air purifiers over the years and Dyson machines are far and away the best I’ve ever used. They are meticulously engineered and the design is aesthetically pleasing.

    I initially setup the machine in my living room, but I decided after a few hours that it would be better suited to a bedroom. Previous Dyson air purifiers that I have used seem to have a much larger oscillation range as the whole unit moves. On this new PH04, only the fan slits oscillate. You have options for 45º or 90º. With that in mind, I placed the machine in a corner at an angle to provide maximum airflow in the room. As far as I can tell, it is doing its job very well. The air definitely smells cleaner in the room. Bonus: No more dog odor! (The dog sleeps in this room a lot).

    As for setting up the machine, it could not have been simpler. I was already using the Dyson app with my other machines so it was as simple as selecting “Add new machine.” Everything was ready to go in under a minute. The app itself provides a wealth of information about the air quality in the room and it also allows for easy control and scheduling of the machine. Most of the same info is also available on the screen of the PH04.

    As it has been relatively humid in my area lately, I’ve not yet had an opportunity to try out the humidifier portion of the PH04, but I look forward to doing so. Would I recommend this machine? In a heartbeat. I expect years and years of fresh, clean air in my bedroom with nary a hint of doggie odors.

    Hi – we’ve been a Dyson air purification fan for years and just got this machine to also help humidify the air. We have a young baby so humidifiers are running through the house. Once we started this machine, added it our app, and got it going, it really shined. The air is so clean without dust, smells go away fast and the baby breathes nicely without the dryness.

    I was extremely excited to get this out of the box and running! Once out of the box, setting up the unit and also getting it connected to my Dyson app was super easy. You just hold your phone up to the fan, easy enough right. As for performance, it’s on par with other Dyson fans and purifiers I’ve had on the past. With someone with two dogs and allergies this is a must for my home. The humidifying is a new feature to my previous Dyson fans and so I’m looking forward to that this winter. I currently have the fan and humidifier settings on auto and everything is great. Again, super simple.

    We have 2 automatic cat litter boxes and no matter how clean they are kept or how many air fresheners were plugged in the house still had that litter box smell. After setting up the Dyson Purifier Humidify + Cool near the boxes it didn’t take long for us to notice that “the smell” was gone. Not only was the smell gone but the entire house had a clean air “fresh smell”. We found the automatic setting to be the best setting for our needs. I recommend this Dyson Purifier Humidity + Cool which will make your home smell great. Helpful hint :
    The instructions downloaded were not the best. Better to download the Dyson Alexa app for clearer instructions.

    I couldn’t wait to unplug this air purifier/ humidifier when I received it. Setup was simple and the unit connected to my home wifi effortlessly.

    I have a few other Dyson purifiers, without a humidifier, and I can see the humidifier will be a great help, especially in the winter when the furnace or fireplace are frequently used. The way the unit breaks down the types of pollutants is impressive. The water chamber holds a significant amount of water so I don’t think it will need to be filled too often.

    Great product so far!
