The value of the existence of household appliances is to enhance the comfort and delicacy of home life, so whether it is a large appliance or a small electrical appliance, the importance cannot be ignored. However, it must be admitted that the "moisture" of the home appliance market is very deep, and if you do not have an in-depth understanding of electrical appliances, it is easy to step on the pit and pay tuition.
For example, the following 4 kinds of household appliances, "affordable may not be able to afford to use". This is not an exaggerationIt's not that the product itself is a problem, but it's easy for businesses to "exploit loopholes" and then hollow out consumers' pockets
Many people have a "prejudice" against water purifiers, not the water purifier itselfIt's that the business has made the reputation rotten
If you have used a water purifier, you will know that the value of this electrical appliance is recognized, and it can indeed filter out some impurities and heavy metals in the urban tap water, so it is necessary for families to invest.
But when it comes to investing, it's easy to pay tuition. BecauseThe real cost of the water purifier is not a one-time investment, but a later "maintenance"., that is", ".Replacement of the filter element
There are too many merchants who deliberately discount the ** of the water purifier (in fact, the machine itself is not valuable),On the contrary, the "replacement" of the filter element will give you a clear look
The PP cotton filter element should be changed once every 3-6 months; The activated carbon filter element is changed once every six months; The ultrafiltration membrane is changed once a year; RO reverse osmosis membranes are changed every two years ......
When the merchant gives a "suggestion" to replace the cycle, in fact, the consumer will "enter the pit". Because of the ** of these filter cartridges, each one is lifted** grid. In fact, the normal price is: 30 yuan for PP cotton, 30 yuan for activated carbon, 50 yuan-200 yuan for ultrafiltration membrane, and 50-500 yuan for RO reverse osmosis membrane.
Those filter cartridges that cost five or six hundred yuan, or even thousands of yuan, are in the final analysis reaping the IQ tax of consumers. So if you want to invest, be careful.
Water Purifier Purchase Guide:
First Principles:Don't buy too expensiveWhether it is a built-in ultrafiltration membrane or RO reverse osmosis membrane, ** is controlled within 2000 yuan (no matter how expensive it is, it is the brand premium).
Second Principle:Let's start with the composition of the filter(Choose RO membrane for drinking pure water, and choose ultrafiltration membrane for drinking mineral water).Let's take a look at the replacement cost of the filter element equipped with this model(Combined with the regular price of the filter cartridge I mentioned above).
Another reminder: Don't listen to the merchant's filter element "replacement cycle" or the "remaining days" displayed on the app, the specific time to replace depends on the situation, becauseThe water quality of each area is different, and even the cleanliness of the household pipe network in each community, the number of cleaning times of the reservoir, etc., will affect the service life of the filter element
Before I used the dishwasher, I always felt that it could free my hands, and it must be very fragrant. However, after the actual installation, you will find that there are only three or five dishes and chopsticks for eating, and you can brush them by hand, and you can save the trouble of "plating" the dishwasher.
And unlike other appliances, the "consumables" of the dishwasher are really amazing.
Dishwashing powder, dishwashing blocks, dishwashing liquid, dishwashing pods, soft water salt, rinsing agent, deodorant fragrance, body cleaner, ......
These are all "consumables" for dishwashers. Many people may say, can I do without these? After all, these will not be less than 300 yuan.
In fact, although these so-called "consumables" are more gimmicks than practical, they also have a certain role, such as dishwashing powder is used to remove grease, dishwashing blocks are used to remove oil stains and watermarks, soft water salt is used to soften water quality and prevent scale, and body cleaners are used to clean spray arms, filters and pipe ......
For most ordinary families, the cost of using a dishwasher will not be less than a thousand yuan per year, so in my opinion, the dishwasher is really a "consumable assassin".
Dishwasher Consumables User Guide:
For users who have invested in dishwashers, in the purchase of consumables, they can actually reduce their expenses to a certain extent, and do not be harvested by the bells and whistles of consumables in the market.
In general, the consumables of the dishwasher can be combined and matched according to the following scheme, which can not only ensure the cleaning effect but also reduce the cost:
dishwashing powder + soft water salt + rinse; dishwashing block + soft water salt; dishwashing liquid + rinse; multi-purpose dishwashing liquid; Dishwashing pods (slightly more expensive).
As for the "deodorant fragrance", it is dispensable. Body cleanser, theoretically, can be used once every 1-2 months.
In the same way that drinking water safety is important, the cleanliness of the air is also being paid more and more attention. Especially in families with babies and young children, it is common to have an air purifier.
After all, the air purifier can purify the impurities, dust and formaldehyde and other free substances in the air while circulating internally (the premise of purifying formaldehyde is that the air purifier is equipped with an activated carbon net).
However, it is undeniable that the cost of "consumables" for air purifiers cannot be ignored.
Generally, the filter element of the air purifier is composed of filter cotton, Haipa filter and activated carbon mesh, especially the Haipa filter, which needs to be replaced every once in a while, so the cost of use should be paid attention to.
The air purifier filter on the market is generally a "composite filter", that is, there are both HEPA filters and activated carbon filters in the filter. Generally this kind of filterThe normal replacement cycle is 3-6 months
In fact, this replacement cycle is relatively "frequent", so the cost of the filter has to be concerned. And if the price of the purifier filter purchased is more than 300 yuan, you should be cautious.
BecauseThe normal ** of most filters is basically between 99 yuan and 300 yuan, even if it is a better composite filter, it will not exceed 500 yuan.
Air Purifier Buyer's Guide:
The first principle: the same do not buy too expensiveIt is recommended to control the budget within 1500 yuan
The second principle: first look at the composition of the filter screen (there should be a primary filter screen, a high-efficiency HEPA filter, and an activated carbon filter), and then look at the replacement cost of the filter screen (combined with the normal filter mentioned above).
Rule 3: The lower the noise level, the better! Since the purifier needs to be kept running on for a long time, the noise must be low, especiallyIt is a purifier for children's rooms, and the decibel level should not exceed 35db
Whether it is a ducted fresh air system, wall-mounted fresh air or cabinet fresh air, each of them should be replaced with a regular "filter". At this point, it's similar to an air purifier.
Since the air purifier is internally circulated, the filter replacement cycle is relatively long. The fresh air system needs to be purified by inhaling outdoor air, so the replacement cycle is very short. Generally, the filter should be changed once every two months
In terms of the configuration of the filter screen, the purification composition of most fresh air systems is: filter cotton + primary filter screen + high-efficiency filter screen + activated carbon screen, and some cabinet fresh air is equipped with electrostatic precipitator.
among othersThe filter cotton needs to be cleaned regularly, the activated carbon mesh needs to be dried regularly, and the primary, high-efficiency filter screen needs to be replaced regularly
Filters for wall-mounted fresh air systems and cabinet-mounted fresh air systemsNormal**Generally within 100 yuan。And the filter screen of the ducted fresh air system,It's basically around five or six hundred yuan。Therefore, when choosing a fresh air system, you must understand the cost of the product equipped with a filter, so as to avoid the experience of affordable and unaffordable chicken ribs in the later stage.
For large appliances such as fresh air systems, in fact, there is no need to invest in many ordinary families. This is especially true in cities where air quality is okay.
The main value of the fresh air system is to ventilate and purify the air at the same time. The biggest effect is to reduce indoor PM2The value of 5 is followed by reducing the content of harmful gases such as formaldehyde and benzene in the room. So there is not much need to invest.
AbsolutelyIf you have high requirements for home life and high requirements for the cleanliness of the air, you can install it rationally
Fresh air system selection guide:
If it is a house that is being renovated, it is recommended to first consider the "ducted fresh air", which can be hidden into the ceiling together with the ** air conditioner. If it has been renovated, you can choose wall-mounted fresh air. The cabinet fresh air system is not recommended to be put into the cabinet fresh air system because of the large size of the main engine (and it also needs to go through the pipe).
In addition, the most important parameters for purchasing a fresh air system are:"Fresh air volume".According to the national standard, the fresh air volume per person per hour should not be less than 30m, so this point needs to be focused on (due to the wind damage of the pipeline, the larger the air volume in theory, the better, but the larger the air volume, the greater the noise, and the noise value should be paid attention to at this time).
