I like to make delicious food , For the health and safety of the family , So that they can eat healthy food . Food can't do without water , Water is the source of life , Water quality safety is very important . According to the World Health Organization , human beings 80% Our diseases are related to the insecurity of drinking water .
At present, the water source for families is tap water , It looks transparent and clean , Is it really healthy and safe ？ In recent years , Water quality safety issues , More and more people pay attention to , All kinds of water purifiers 、 Water purification pots are also on the market .
A lot of people , Including myself , I didn't care before , I still remember a long sentence hanging in the mouth is ：“ It's so pretentious now , When I was a child, I drank directly from the tap ！”
however , Ever since the water cut off one day , I changed my mind ！
The tap water just came after the water cut off , It's cloudy , A lot of sediment , Yellow , With a fishy smell , The smell of rust at that time . What to do at this time ？ The only way to do that is to let the water out 、 water 、 Keep the water flowing ...... Until the water becomes clear .
And then we start cooking with peace of mind , cook a dish , Wash the clothes ......
however , I don't know if you've thought about it , Why is the water so dirty ？ Where do they come from ？
Water is piped from the waterworks to the home , And the pipes have been buried underground for years , It will rust 、 Ageing 、 Accumulate sediment . The water is always flowing , We can't see the fine sand , The water stopped when the water stopped , Sand and rust have settled down , When the water comes again, the rust will be all up as soon as the silt is washed away , And then we see ！
actually , With the rapid development of modern industry , Water pollution is becoming more and more serious . Except for the sand 、 Redworms 、 Visible impurities such as rust , And the residual chlorine 、 bacteria 、 Invisible hazards like heavy metals . All of these affect people's health .
silt ： It's related to the cleanliness of the water source
Redworms ： It is usually caused by secondary pollution of water pipes and water tanks
rust ： The aging of water transmission pipeline leads to
The algae ： Eutrophication of water source and various secondary pollution
Residual chlorine ： The residual chlorine in tap water reacts with organic matter in water , Chloroform and so on
bacteria ： The water pipe network is in disrepair for a long time 、 The water tanks in high buildings are polluted , It's easy to overgrow bacteria in water , Affect health
Heavy metals ： The discharge of industrial waste water causes lead in the water 、 Mercury and other heavy metals exceed the standard , Not only does it affect children's physical and intellectual development , It's also harmful to adult health .
last year , I started a Lycra purifier , It has double filter system imported from Italy , Even bacteria can filter out , Come out and drink straight , also 3 Second hot water , Drink as many as you want , Don't wait for , Very convenient , Love it ！
however , If you cook 、 I also hope to use healthy water for cooking , If you pick it up with a cup , At most one time 300 ml , That's not very convenient ！
later , I found that Leica's family has produced another water purification kettle with double filter elements imported from Italy , It's a sister version of the water purifier , It's the same as a drink purifier 2 A filter element , Come out and drink straight , It's just that there's no heating function , But it's convenient to pour water , Cooking 、 cook a dish 、 Drink lots of water , It's very convenient for me to make delicious food .
First , Let me praise the Lycra's packaging , Double cartons , Not afraid of violence . and , The cartons outside are not random waste cardboard , It's very formal with the Leica family LOGO Standard cartons for .
It's packed in color boxes , Clear and beautiful .
Open the carton , The inner package is tightly clamped , The product will not shake or shift , It's not broken .
The first thing I see is the kettle packed in plastic bags , Ultrafiltration filter cartridge packed in cartons , And a manual .
The biggest difference between Leica water purifier and other water purifiers is that it has 2 A filter element .
On the left is the double flow guide high efficiency filter element , For narrative purposes , I call it primary filter element . It's made up of a front filter 、 ion exchange resin 、 Coconut shell activated carbon 、 Post microgrid 、 It is composed of five layers of filter screen , It can filter a variety of impurities , As big as sand 、 egg 、 particulate matter 、 Suspended matter 、 Sand and so on , As small as heavy metals 、 Filter the chlorine 、 compound 、 Pesticides, etc .
The one in the middle is the ultrafiltration filter , from 0.01 Micron hollow fiber membrane , The pore size is only the diameter of bacteria 1/50, It can be filtered out 99.99% Bacteria of .
Because of it 2 The cooperation of two filter elements , therefore , The filtered water can be drunk directly , There is no need to heat and boil , And health and safety .
It's summer , Children are very sensitive to temperature , I don't want to wait for boiling water to cool down , This water purifier just came in handy .
On the far right is the hand pump , It is used to activate the ultrafiltration filter element .
Next , Let's install the filter element .
First step , Unpack the primary filter element .
The second step , Soak the primary filter element in water 15 minute .
The third step , Take out the hand pump and ultrafiltration filter element .
On the right is the ultrafiltration filter element .
Step four , Take out the pump cap , Screw the ultrafiltration filter element into the pump pipe .
Step five , Squeeze the water out with the pump cap , Over and over again 5 Time .
Step six , hold 2 A filter element in accordance with the good , Compress .
First use , After filtering 5 After a liter of water , You can officially enjoy the clear and clean water .
Put on the lid , The front end has a spring type water inlet , No need to open the cover , You can add water . A timer is mounted on one end of the handle , It's a flow and time dual sensing device , The indication is clear when the filter element needs to be replaced .
The lid is tight , I'm not afraid of falling when I pour water vertically , I like this very much . ha-ha , Last time I had a clean water bottle , When I cook, I pour , The lid fell into the pot , Embarrassed !
Lycra water bottle is white , The funnel inside is light blue , It looks very beautiful . On the right is another brand of water purifier , It's also popular on the market . A comparison between the two , Leica's clean water bottle looks like a few streets away from others , first impression , Leica wins .
however , Let's not mention the beauty , The most important thing is to see who has better filtration performance .
therefore , And then I got a couple of reagents , Let's do some small experiments on them , Actions speak louder than words ！
The following experiments , I did it in order , Every time before you do it , After all the cups are washed , Then rinse with the corresponding group of sample water 2 Time , Let's move on to the next experiment , Make sure the data is reliable .
Every little experiment , Share in 3 A set of , Left 1 It's a brand of filtered water , In the middle is the filtered water from Leica's kettle , Right 1 It's tap water .
experiment 1： Residual chlorine test
Residual chlorine test agent and standard colorimetric card
Take from each group 10 Milliliter of water , drop 2 Drop the reagent , Shake well . When it first drips in , Show 3 There are not many groups , The water cup on the right is slightly yellow .
Standing 10 Minutes later , On the left 2 All of the experimental groups performed quite well , The color of the control group was yellow , The total chlorine value is high .
experiment 1 Conclusion ： Both kettles are great for residual chlorine filtration ！
experiment 2：PH test
Experimental process ：10 Drop into each milliliter of water sample 2 Drop indicator .
experimental result ： A brand kettle is slightly sour , Lycra kettle is neutral and slightly alkaline , Tap water is more alkaline .
experiment 2 Conclusion ： The water filtered by Lycra water purifier is healthier .
Because normal blood PH Values in 7.35~7.45 Between , For alkaline constitution , But these people only account for 10% about , More people's body fluids PH stay 7.35 following , The body is in a sub-health state between health and disease , It's called acid constitution in medicine . The situation of these people is often not solved by drugs , But it can be improved by drinking weak alkaline water , Many natural mineral water is neutral and slightly alkaline . therefore , At present, everyone agrees that neutral and weak alkaline water is relatively healthy water .
But for those who are in the basic system , Drink more alkaline tap water directly , It's also inappropriate .
experiment 3： Ion detection （ Represents the hardness of water ）
The process ：20 A milliliter of water 2 Drop the test reagent , When it just drips in .
result ：2 The experimental group was blue , The tap water control group showed purplish red .
Conclusion ： after 2 After filtering in a clean kettle , Some ions drop , The hardness of the water decreased , This kind of water is not easy to scale .
In ion filtration experiments ,2 Every water purifier did well ！
experiment 4： Rust filtration test
Experiment preparation ：2 Add the same amount of Fe2O3 powder into each beaker , stir .（ Iron oxide is the component of rust .）
experimental result ： The water filtered from a famous brand kettle is still red , The water filtered by Lycra is clear .
（ The result is amazing ！）
Because of the excitement , Finish the experiment , I found that there was water at the bottom of the Leica clean kettle on the right, and I forgot to pour it , So there's a lot of water , But the water is transparent , It's still telling .
Conclusion ： In the rust filtration test , The performance of Lycra water purifier is obviously better than that of a certain brand , Perfect victory ！
I'm obsessive-compulsive , Pour out the water from the bottom of the Lycra clean kettle , Refill the rust water , Filtered again , this time 2 There's as much water in the group .
Take a closer look at the side of the Lycra clean kettle , The blocking of rust , The key is to rely on the ultrafiltration filter .
And a certain brand of water purifier only has primary filtration , So it basically doesn't filter rust .
Pull out the filter element , It's just a funnel , There is nothing .
that , Someone will definitely ask ：“ Then why 2 A filter element ？ Since the ultrafiltration filter element is so good , I just need to buy this one ？ It can also save money , This can last a year .”
The answer is , no way . Because the two filter elements have different functions , In short, the primary filter is bigger , Ultrafiltration, bacteria and other small , If only ultrafiltration , It has such a small aperture , It's going to get clogged up by the big stuff in the tap water . You have to match the two , work in cooperation with a due division of labour , I'm not tired of working ！
experiment 5： Industrial pollution filtration （ Blue ink Demo ）
2 A cup of 350 Ml water , Drop in separately 3 Drop blue ink .
hold 2 Pour in a glass of water 2 In a clean kettle .
Although I pulled out the filter element and cleaned it several times , however , The water filtered from a certain brand kettle is still red , I can't see the problem of blue ink clearly . On the right, the water in Leica's clean kettle is clear .
later , I still don't give up , Pull out the filter element of a brand water purification kettle , Washed and soaked all night , Until the water from below is clean , Another experiment was done .
experimental result ： All's well that ends well , Both filtered water is clear .
The experimental conclusion ： It means that both of the water purifiers can filter out the blue ink .
in summary , A certain brand of water purifier has a certain filtering effect , Lycra's water purifier is even better , The filtered water is cleaner ！
But in the actual use process , Many of the details are more in place in the design of Lycra water purification kettle ！
1, The design of the intake
2 Each water purifying kettle is designed with a water inlet , The aim is to allow people to fill water without opening the lid . Lycra's intake is a little bit forward , It's a punch , No hands , When there is water, it will open automatically , And a brand kettle is open type .
After the cover of the water inlet of a certain brand is opened , It's not easy to push it down , Anyway, that's my pot , Not very flexible .
2. The design of the nozzle
There's a falcon like arc at the outlet of the Lycra water purification kettle , No leakage, no outflow . For example, when I do experiments , It's pouring directly from the mouth of the pot 10 Put one milliliter of sample water into a small beaker , It's hard to pour a certain brand of kettle , There's a lot of water coming down the spout , Make the outside of the pot full of water ; The Leica pot is clean , Not a drop will flow out , The whole pot is clean .
3. The design of the timer
2 Each water purifying kettle is designed with a timer , A brand of clean water bottle timer is on the lid , Lycra's water bottle is on the handle .
Remove the cover , The timer of a certain brand of water purifier has also been removed , And Lycra's because it's on the handle , Always connected to the sensor .
Take a close look at , Leica's timer has nothing to do with whether the lid is removed , It's obviously connected to a circuit board , It can detect traffic and time at the same time , therefore , When the filter element needs to be replaced , Tips are more accurate .
then , After taking off the lid of a brand water purifying kettle , This timer （ The red circle place ） Take it off, too , And it can be taken down and cleaned at any time . The manual says , It claims to be able to filter water 、 The water quality （ hardness ） And the use time of the filter element for triple detection . then , I don't quite understand , The lid didn't touch the water all the time , How to detect the filtration and water quality ？ I can't understand . however , Calculate usage time , That might be possible .
4. Use time of filter element , Lycra's longer
A brand of water purifying kettle ,1 A primary filter element , The usage time is 4 Zhou ;
Lycra water purifier ,2 A filter element , Primary filter element 6~8 Zhou （ According to the flow rate and water quality ）, Ultrafiltration filter element 1 year
in summary , If 2 There's a kettle in front of you , Which one would you choose ？
There is no doubt about the result ！
Ever since the Lycra water purifier , Now my family cooks , cook a dish , Make tea , Drink lots of water , They all use it , Straight water , More at ease ！
A clean water bottle is only a few hundred yuan , But it's equivalent to cooking with mineral water every day , Every day 1 It's less than one yuan , Make a lot of money ！
Especially when it's hot , My son just drank the water from Leica's kettle . however , I like to drink from the Lycra purifier , Because I like to drink in summer 40 The degree of water , I drink in winter 60 Of water , Anyway, Lycra purifier 3 Second hot water , Very fast ！
